bmw' s new x2city folding electric kick scooter is a potentially landmark product for the brand in many ways, not the least of which is that it is the first bmw product that will be sold and serviced outside the global bmw dealership network .
. for safety, the electric motor is not activated when the vehicle is powered up, but after the first kick. egret one - s, actually, can also be used as a traditional kick scooter, without the use of the electric motor. if you use it as a traditional kick scooter you need to be careful both for its high acceleration and the braking distance. with a single charge you can travel more than 20 kilometres (almost 22) thanks to the engine brake that functions with a regenerative braking mechanism. the cornering grip is quite good, but perhaps shock absorbers could be “softer”, although
compared with the ecoreco, the $ 1, 000 emicro one is a revelation. it doesn' t look like an electric scooter at all - - no power button, brake or throttle levers, just handlebars, wheels and deck. that' s because it' s an electric kick scooter whose motor automatically comes to life when you kick off with your foot. it extends your stride, going faster and faster each time you push - - which means you' ll still be getting some exercise, particularly kicking uphill .

(most electric skateboards and hoverboards don' t have that range .) and most importantly, the scooters have a nice big handle so you don' t slide off .

electric kick scooters, goofy they may be, are a particularly good answer to the last mile problem. they' re light enough to sling over your shoulder, and small enough to fold for stowing in the trunk of your uber / tesla / hyperloop pod. they' re easy to ride just about anywhere, require minimal physical exertion, and are relatively affordable .
the x2city operates as a traditional kick scooter and the rider needs to propel it up to 6 km / h before the electric drive can be engaged, and even then, there is no traditional
throttle
. the operating unit on the handlebars offers five speeds in quantum jumps of 8, 12, 16, 20 and 25 km / h. the above image is all we have to imagine how that works, and it appears to work like a paddle - shift on a car, though operated with the right thumb .
with such a compact and ergonomic design, it barely even looks like an electric scooter. the stryder simplifies things by folding to half its size with one click, making it perfect for trains, or tucked away in your home or office. weighing just below 11kg, you can trolley it easily without breaking a sweat !
the bus, train and shuttle only take you from point a to point b. could a portable electric vehicle get you the rest of the way there ?

it would be perfect, rather, except for the fact that anyone riding a scooter looks like a dweeb. sure, scooters are practical, efficient, and useful. they' ve been a good idea for a long time, since well before they were even electric. but they' re not cool. they' ve never been cool .

as a product, it is a little difficult to make informed comment at this point. the x2city operates as a traditional kick scooter and the rider needs to propel it up to 6 km / h before the electric drive can be engaged, and even then, there is no traditional

the second thing you need to know about scooters is that there' s a decent chance you' re going to be riding one soon. it might be a fancy electric seated thing from some hip startup, but just as likely it' ll be an old - school, kick - push - and - coast, razor - style ride. why? because we need a way to move around that isn' t inside a car .
the emicro is smaller and far lighter than any other electric scooter at just 16. 5 pounds, and you can keep on kicking with minimal friction even after the battery runs out. sadly, there' s no springy suspension to help cope with san francisco' s gritty streets. i' d definitely recommend it if you don' t mind a sidewalk - only affair .
two of the cells stacked give ample clearance for a proper internal mount. conveniently enough, a regular razor scooter has enough material between the wheel mounts to hold 4 cells, 2 stacks of 2 .

for the last few weeks, i' ve used an electric scooter as part of my daily commute. it' s called the uscooter. it costs $ 999, and it' s coming to the united states after a successful debut in china. it' s got a range of 21 miles and hits 18 mph with just a push of my right thumb—on a scooter, that feels like warp speed. every time i ride it, i feel ridiculous. but as i zip up and down the sidewalks of san francisco, bag slung over my shoulder at the end of a long day, i do it like the fat kid strutting in that
haters gonna hate

it is fair to say that we all seek complete safety while riding. it is an essential requirement that has to be met. the e - twow electric scooter not only meets this safety requirement, but also exceeds the expectations in this particular department. it provides users with complete stability during riding thanks to the equilibrium between its design, structure and weight distribution. e - twow is equipped with a remarkable double braking system which ensures an entirely secure ride .
i decided to use a microcontroller to translate between the two instead of the awesome ghettomongous discrete - part boardamathinger that i built for the first scooter. a bit of messing around with blinkenlichten on a miters stk500 and i was in business .
i have plenty of experience riding bikes, though. so why not a folding electric bicycle? watching my fellow caltrain riders struggle to lift their bikes onto the train was enough to put me off. folding electric bikes might fit into the trunk of a car, but i wouldn' t dream of taking something so heavy and cumbersome on the bus - - and they' re expensive, too, with many costing upwards of $ 2, 000 .
regardless, there’s 29. 6 volts of 4ah lithium polymer cells, a (former ?) 100 amp motor controller, and a very chunky brushless motor shoved into the space of a razor scooter. i think it’s pretty damn awesome just for that .
make no mistake, just like a bicycles, these kick scooters will need servicing too. oiling of chain especially after riding in the rain often is a must to keep things moving smoothly. while it may not be frequent and immediately obvious, you will need to consider replacement parts like tyres, batteries, belt and charging adapters. it pays to work out the cost and availability of these parts up front to make sure that you know the total cost of owning and running this. other key considerations are charging time, distance covered per full charge, speed and maximum riders weight. we list these parameters for each of the kick scooters in our list below but to give you an idea of what to expect, check out our table here .
. for this reason driving this scooter is funny as well as useful, since you can travel short distances in short time. the vehicle comes with a transformer similar to those used for laptops to charge the batteries and it only takes about 6 hours to recharge it fully .
next, each rail had to get a chamfer machined on its outside - facing edges. the interior of the razor scooter’s chassis extrusion has a radius of about 2mm. i cannot duplicate this precisely, so a messy one - size - fits - all chamfer takes care of it .
here’s a sample section of a razor scooter chassis. it’s a one - piece extrusion, which is great for mounting stuff to. the part above the flange (which is actually the underside, if you can’t tell from the scuffs) is 63mm side with a 57mm inner width .
the case for scooters gets even harder to make when you look at the price tags, which are much higher than the $ 200 or so you can snag a hoverboards with. ducorsky defends the $ 999 price of the uscooter as the rightful cost of making a safe product (you know, one that won' t catch on fire). he also notes that hoverboards are harder to ride, can' t handle hills, and are much more toy than transport. plus, even at a grand, the uscooter is one of the cheaper electric kick scooters on the market. ecoreco' s m5 costs $ 1, 250; a similar model from go - ped is about $ 1, 500 .
first time riding? no problem. choose eco riding mode and enjoy smooth, gradual acceleration. pros can switch to turbo mode for maximum power and acceleration. our regenerative braking allows for safe and responsive braking, ensuring great control even on down hills. stryder is the perfect e - scooter for everyone .
not all electric scooters are equal, of course. ecoreco, one of the best - known brands, makes models built like a tank, with fold - out handlebars broad enough to make steering a cinch. but even the company' s smallest, lightest $ 1, 100 + ecoreco s5 model - - at over 28 pounds - - was too heavy and bulky for me to easily hoist to the overhead luggage racks on caltrain or hold upright on a crowded bus. and when i was riding, its rear brake would often make the scooter skid instead of quickly bringing it to a stop .
also, there is the option of a scooter with seat or without one. while we find the seat version unappealing and unnecessary especially when you only have a short distance to cover and when you have already sat in the train or car before jumping on one of these, its worth considering should you find one useful .
electric skateboards have no problem with speed. the $ 1, 500 + boosted dual +, a sleek longboard with orange wheels, travels at up to 22 miles per hour and can climb hills with a 25 percent grade. that' s beyond my budget, but even when i tried the $ 700 yuneec e - go board, whose belt - driven wheels top out at 12. 5 mph, i constantly felt like i was about to crash and die. turns out that even though these electric skateboards have handheld remote controls to manage your speed, you still need to be pretty good at balancing on a skateboard to stay upright. i' m not .
the business end. the relevant power transmission implement – there is only 1 – is housed completely in the rear wheel. it is a 80mm diameter custom - built 3 - phase brushless dc motor, conveniently hidden within the confines of a 125mm scooter wheel. maximum power on it is probably about 1000 watts. i have yet to properly meter it .

this is sacrificial vehicle # 2, another junked scooter that was sitting around miters. i’m not sure if it’s an older generation or what, but there are quite a few structural differences compared to the new a3 model i’m converting. it’s certainly beefier in the folding joint (0. 1″ formed steel plate !) and brake area, and there is more material in the chassis .
a battery management system with integrated power electronics is designed to ensure a range of 25 to 35 km in everyday use. a specific charging unit with magnetic connector makes for easy charging using the exterior charging socket on the scooter or directly at the battery itself. the battery is charged using a conventional household socket and it takes approx. 2. 5 hours to charge an empty battery .
♥ quick folding, more lightweight and convenient: quick folding and unfolding, small size, lightweight; easy and flexible to carry on bus or subway, put in trunk of car or under office desk. the weight is balanced and it' s light and easy to carry ♥ unique design of left and right pedals according to ergonomics, which avoids the discomfort brought by the one pedal design of traditional scooters and allows you to ride as you wish comfortably ♥ acceleration protection: acceleration protection is initiated only when people is standing on scooter, preventing potential safety hazard in case of touching accelerator when parking ♥ constant speed cruising: scooter will cruise at a constant speed when riding at a speed for 3s, avoiding the aching pain caused by pressing accelerator for long time and enhancing the riding comfort ;
these scooters are all starting to hit american shores, all banking on the same thing: that there are lots of people looking for a faster, easier way to get to the grocery store or the subway station. they' re hoping that scooters are just the right mix of powerful, portable, and useful. they' re also hoping to deal with some important questions about where you can and can' t legally ride an electric scooter. ducorsky wants to sell uscooters to you and me, but he' s also imagining them as a great way for pilots to get around airports, for cruise patrons to see the sights on shore, and for managers to get around factories .
there are so many markets for this thing ,
he says. it' s hard to disagree .
i may not be doing sweet tricks anytime soon, but my electric scooter is an amazingly efficient way to get around. it turns 20 - minute power - walks into effortless five - minute rides. it' s tripled the size of my immediate vicinity—i' ve been riding to coffeeshops and stores i' d never patronize otherwise. when i' m not riding i can fold it up and carry it, or sling it over my shoulder to go up stairs. at 24 pounds, it' s no featherweight, but as i squeeze onto the morning train, i pity the people begging strangers to move so they can fit their bike. with the 21 - mile range, plus the energy recouped by a regenerative braking system, i only need to plug it in once a week, for a few hours .
you' ve probably seen them whiz by on crowded city streets. electric scooters, motorized skateboards and hoverboards are becoming legitimate forms of urban transportation - - and it' s not just kids who ride them. there' s a whole wave of new vehicles strong enough to support the weight of an adult, yet fold up small enough to carry onto public transportation or in the back of a miata .
as the mechanicals were nearing completion, i started playing with the electronics. the r / c airplane controller requires a 1 to 2 millisecond long pulse spaced every 20 milliseconds, which is a hobby industry standard for control signals. however, the electric bike throttle i was going to use puts out an analog voltage from 0. 8 to 4. 2 volts. this is, again, a different industry standard control signal .
the uscooter was born about five years ago, under another name: e - twow. (it stands for electric two wheels, and you pronounce it e - 2. it makes no sense .) it' s the work of romanian engineer sorin sirbu and his team in jinhua, china. sirbu' s friend brad ducorsky helped with the development and is now responsible for the improved, better - named americanized version .
you need to know about scooters is that it' s impossible to look cool riding one. when you ride one, people look at you with disdain. they shout things like ,
you' re the problem !
and
get off the sidewalk !
( seriously .) they try to get in your way as much as possible. even people on hoverboards and electric skateboards judge you. these are just facts .
the e - twow electric scooters are not only environmental friendly, but also wallet friendly. e - twow is the most economical vehicle ever emerged on the market with an amazing energy consumption of only 6. 15 wh / km at a speed of 20 km / h and with the cruise control function turned on. this is without a doubt an unparalleled performance in terms of consumption and a clear sign that e - twow is truly unique .
the new 15 mph (25 km / h) x2city has an electric range of 25 to 35 kilometers (15 - 22 miles), and folds to a size that bmw claims is smaller than a folding bicycle. viewed in comparison to the wider offerings of the marketplace, none of those qualities are game changers, but it does offer the bmw experience to new audiences for the first time in more than 70 years. bmw has been making bicycles since 1945, cars since 1929 and motorcycles since 1923 .
thankfully, there' s another scooter that handles streets just fine, and works even better. the $ 1, 000 uscooter (aka e - twow) is hands - down the most convenient vehicle i' ve found for navigating city streets. it has one of the softest suspensions, has the most traction going uphill and is by far the easiest to fold down. even when i carry a heavy backpack, i can get through a work week (roughly 10 miles of riding, partly uphill) without plugging into a charger .
the uscooter' s the only one i' ve tried that' s clearly designed for commuting, too, with a beeper and built - in led headlights and taillights so cars can see me at night. it has cruise control, and its front electric brake stops me more quickly and safely than ecoreco - like designs. sure, it' s a little jerky, front - heavy and doesn' t look particularly stylish. but i don' t care about that when i' m leaving bicycles in the dust .
there are plenty of possible last - mile solutions: bike - share programs, segway rentals, folding bikes, even skateboards. in asia, for instance, a number of cities have experimented with people riding a variety of small, economical
personal electric mobility devices
to get from public transit to their destination .
they are a low - carbon, affordable, and convenient way to bridge the first and last mile gap ,
raymond ong, an assistant professor at the national university of singapore’s department of civil and environmental engineering, told eco - business .
that means the scooter is likely to be extraordinarily good. bmw' s greatest asset is its reputation and the values associated with the name and the logo: robust, reliable, technologically advanced, easy to use and much better than average. those premium qualities enable bmw to charge a premium price and there' s no more critical time to deliver all of them than when addressing a new audience that you are hoping to upsell at a later date. you only get one chance to make a first impression and for a premium brand like bmw, the quality of that initial experience is paramount .
most lipo cells of this capacity are around 5. 5mm to 6. 5mm thick, with the thicker being the higher discharge - rated ones. maxamps advertised their cells as 6mm thick, which, in a 3 - stack, left me less than 1 millimeter of play inside the scooter’s 19mm tall internal channel. the original battery mount was going to be “bottomless”, with the supports for the cells coming only from the sides and the bottom capped by a wide tape, such as fiberglass strapping tape or kapton tape. my 3s pack with 6mm thick cells (which is not high discharge, unfortunately !) did fit in a test .
it does have its flaws. the only throttle settings seem to be
barely moving
and
land speed record ,
so you' re always speeding up and slowing down and speeding up and slowing down. the worst part of the whole experience, though, is the folding mechanism. opening it is easy enough: press down on the back tire' s cover until the steering column clicks out, then pull it up until it' s vertical. but to fold the scooter back up, you have to push forward on the handlebars, then press down on a tiny ridged lip with your foot until the hinge gives. i call it the shoe shredder, because you' ll rip a sole off trying to get the thing to disconnect. the uscooter has a bad habit of trying to unfold while you carry it, too .
: the legislative void doesn’t recognise the existence of this type of vehicles, because they aren’t walking speed accelerators (within 6 km / h) nor pedal assisted vehicles, nor mopeds (that require the use of helmets and an insurance). in fact they fall under the category of vehicles subject to approval. the german company, however, stated that the designer florian walberg is in a workgroup of a technical committee in brussels that is creating the standards of definition of a vehicle without seat as well as the specifications for the new category of “lightweight electric vehicles”. “our goal is to raise the consumers’ awareness on the future of transportation. we all travel several kilometres daily to commute to work, go to a restaurant or sports centres”. clearly, if these means of transport were more widely used, the legislature would be obliged to find a legal loophole to make them circulate within the law .
bmw' s announcement a folding pedal - electric bike concept called the i pedelec in 2012 shows the issue of carrying secondary transportation within its vehicles has been on the company' s radar for some time, but for some reason it failed to turn the bike into a commercial reality. that' s the i pedelec above, and although the x2city won' t be sold by bmw dealers, the following excerpt from the announcement press release leaves no doubt that' s part of the plan: thanks to its low weight of 20 kilograms and the foldable steering unit, the bmw motorrad x2city can be stored easily in the luggage compartment of a small car. it is ready to use after a few easy steps and can take its rider from parking space or city limits to the final destination inside the congested city centre. the compact dimensions of the bmw motorrad x2city also make it easy to transport in the bus or on the underground – the ideal solution for spontaneous and comfortable mobility in areas not reachable by motorised means of transport .

the main advantage of airless tires is that they cannot go flat, resulting in a savings, due to the fact that airless tires will need to be replaced less often. the vehicles outfitted with airless tires are able to carry more weight and engage in more rugged activities .
one of the best parts of the e - twow scooters is their distinctive folding system. the scooters can be fully folded with a single click of the lever on the platform. afterwards you can easily carry and store it any place you desire: under your office desk, in the trunk of your car or in a locker .

update: test video! now it officially exists. low speed only for now, since i b0rked the controller and stuck it in sissy modeâ„¢
after eight months of development, five of which were spent sitting on a shelf at miters, snuffles reloaded finally moved under its own power. and boy did it move… i have already managed to nearly faceplant once on it .
with the project having entered a state of semi - functionality, and with it standing a decent chance of becoming something worthwhile, i’d like to move onto a less whimsical name. while “snuffles” was cute, it just doesn’t have that aura of coolness .
no, it’s not spring returned. it’s cruise control for cool. without caps - lock, and potentially more blood .
i finally mustered up the effort to pull it off the shelf and hook up the last four wires remaining on the thing which had kept it from moving for the past few months. with the help of some friends, we got everything bunched together as a test rig – then decided to call it good and wrapped everything in tape. and good it was. this time, functional cameras are immediately accessible, so expect some “action shots” when the sun comes up .
so why is it “99% ” done? well…. right now, it will probably get me arrested if i take it to the airport (then again, when you’re an mit student, anything will). obviously there needs to be some wire cleaning and rerouting. i don’t have a correctly sized box to house the onboard voltage regulator and r / c signal interface yet. i have a proper e - bike throttle that fits over the handlebars. i also need to make a charge - balance plug for the battery pack .
however, it is at least mechanically sound, and i was able to ride it back from miters. therefore, i know the range is at least 3000 feet minus one railroad crossing .
even with no torque advantage (as a direct drive motor), the acceleration is pretty absurd. it’s not quite the neck - snapping and rider - launching takeoff of snuffles 1, but i do need to hang on pretty hard. it is, however, a controllable launch, and will be even more so when a proper spring - loaded thumb throttle is installed (you know, so i don’t have to hang on with one hand and one leg while twiddling a knob on a stick with the other hand )
this is the “larger” flavor from razor, which has 125mm wheels. with the belly pack, i still have about 1. 5 inches of clearance. not going to be bounding over any curbs or potholes, but it’s enough to get around on bike lanes and sidewalks .
there are four 4. 2ah lithium polymer flat cells inside, and four outside. they are run in series for 29. 6 volts nominal. the packs are rated for 20c discharge (80 amps) and can burst 30c, so i have plenty of reserve battery power. as for capacity, calculation showed that my optimal range at constant power on flat, frictionless ground in a universe with a constant gravitational field at a constant temperature in air with zero viscosity and me approximated as a point mass… is about 4 miles, no entropy generated. realistically i expect far less, and need to do a real rangecheck some time soon. anything above 2 miles is really enough to putz me around campus and into town and back .
with an extension of the belly box, and some custom control electronics, i could conceivably hide all the control stuff inside the tube frame, and only have a throttle cable coming out .
and it weighs this much. with better mounting facilities, it should weigh around 12 pounds. that’s a hair under 6 kilograms for you people in metricworld .
anyways, work will now continue on dressing up the control system. i’ve officially moved past the “90% zone of project - related self - loathing” which occurs with everything i build – i would furiously build it to 90% of the way, then just get sick of it and forget about it for a while. now that i know it works, i should be a little motivated to push it through .
i have kept a detailed build log of this project and its predecessor on this site .
there seems to be a disturbing trend in all my recent projects of everything progressing smoothly and going right, then the whole project grinding to a halt at the last possible second before completion and being wholly unrecoverable without spending an additional hefty sum of money. case in point: tb4. 5 - sp1 for motorama had essentially half the robot become crippled the day before i had to leave for the tournament .
new case in point: snuffles reloaded half - existed for about 30 seconds before the motor controller failed. the failure is undiagnosed at the moment, but probably revolves around blowing a voltage regulator which then shot the controller logic with 35 volts .
here’s some build pics from over the past few weeks, and the (95 %) complete vehicle, along with the half - existance video .
after playing with the analog - digital converter, i made the output leds act as a throttle display meter of sorts, for kicks. full throttle, all leds lit, and they go out in sequence as i let off the throttle. i might actually implement this using a led bargraph chip in the future .
next up was assembling the eight giant lithium - polymer cells without killing myself or burning down buildings .
to solder epic batteries, you need an epic soldering iron. unfortunately, i couldn’t find the epic soldering iron i used at the media lab to assemble a123 cells, which are even more epic than my 4ah lipos. so if you do not have an epic soldering iron, you need an epic soldering tip .
a scavenged rod of copper and some lathe time later, and i had an epic soldering tip which fit a radioshack 40 watt soldering iron, which i do have. the whole thing is 2. 5″ long and is. 400″ in diameter at the larger half .
the brass one was for testing and practice, since a rod of copper is actually pretty pricey these days to just fuck around with .
the bottom battery pack completed after some careful iron maneuvering. the epic tip made the whole operation touch - and - go, exactly what you want for soldering batteries. you never want to park the iron on a battery cell for more than a second or two .
this was a bit of a risky operation since i was laying the cells face - to - face to conserve wiring volume. normally, batteries like this are stacked and the cell tabs folded over one another. one wrong move with the massive solid copper tip and i was probably looking at replacing a cell .
after each joint was made (and its balancer lead installed), it was covered in electrical tape. when all the joints were completed, i slammed the whole thing in a tube of giant heatshrink and parked the heat gun over it .
giant heatshrink should be a primary structural fastener. when it starts tightening down, everything inside sort of scrambles for the lowest volume configuration, and the end result is a very neat package of parts. the pack was embedded into its mount with some also primary - structural double - sided tape .
this pack constitutes cells number 5 through 8. the balancer lead is a standard 3 - pin r / c servo plug, which serves the interconnects between cells 5 and 6, 6 and 7, and 7 and 8.
