In seconds, ShareRoller adds electric power to everything you ride.


ShareRoller is the world's first portable, detachable electric drive that can be attached or removed in seconds from almost anything you ride - mountain bikes, road bikes, hybrids, cruisers, cargo bikes, even share bikes and kick scooters!

ShareRoller weighs only 5.5lbs (2.5kg) and is just 8"x8"x2.8" (20cm x 20cm x 7cm).  It can be carried easily on its own, or in a laptop bag, briefcase, or handbag.  And it can be installed or removed from any compatible bike or scooter in about 5 seconds.  Seriously.

Once installed, ShareRoller's 750 Watts of power will propel you effortlessly at 20mph+ without pedaling for 14 to 20 miles of range (Extended Range version 25-36 miles).  This is no puny 250 Watt 'assist' like many others on the market; ShareRoller packs a full 1.0 horsepower - as much power as a Tour de France cyclist in a sprint! 

With ShareRoller you can glide up hills, power through headwinds, and sail through a breeze on a hot day without breaking a sweat, and without pedaling if you so choose. ShareRoller transforms your wheels by turning every bike (or scooter) you ride into an e-bike (or e-scooter), allowing you to go farther, faster, and with only as much effort as you desire. And since we love and encourage pedaling, with ShareRoller you can always pedal as much as you want - simply use ShareRoller's variable throttle button to choose exactly the amount of assist you desire, exactly like a car's gas pedal.


Simply slide the ShareRoller onto the triangular mounting bracket, swing out the motor assembly, and clip it into place.   Then extend the throttle cable and snap it onto your handlebar mount to place the throttle at your thumb.  Away you go.

The triangular mounting bracket is native to most North American bike share operations (PBSC bike models), and replicated in our Universal Mount for fitment to almost any bike.  Folding bikes and kick scooters have their own custom designed mounts.  All install easily and when removed, leave your bike or scooter pure and unadulterated.  No heavy hub motors, batteries, or controllers to give your bike a permanent case of obesity.


Our Universal Mount attaches easily to the front fork brake and reflector brackets that exist on most bikes.  Adaptor clamps are available for bicycles with disc brakes and top mount brakes.  Once fitted, the ShareRoller can be attached or removed in seconds, allowing you to choose anytime whether to ride an e-bike or a pure human-powered bike.  


Brompton, Tern, Montague, and Dahon, we've got you covered.  Custom designed mounts are available for bikes that aren't accommodated by our Universal Mount.  They won't add a lot of weight (about 1/2 lb) and they won't interfere with the fold.  No need to weigh down your light folding bike with a permanent e-bike kit in order to have the assist on days you want it.


Razor, Xooter, KickPed, and Hudora models are already fitted and ready to go.  Custom mounts attach in minutes using only a screwdriver.  How does a 17lb e-scooter with a 20mph+ top speed sound? 


ShareRoller is 'ready-to-work' on tens of thousands of share bikes in multiple cities around the world.  In seconds.  With no adaptor required!

ShareRoller is 'ready-to-work' on many bike share programs around the world that utilize the 'Bixi' bikes originally developed in Canda.  ShareRoller works on all of these bike share networks without an adaptor becausethey all use identical bikes!  Please note that ShareRoller is not affiliated with any bike share operations, so please check with your local operator before use.  And if it's not allowed, we cannot recommend its use, but please let them know you want to be able to use ShareRoller so you can transform your bike share's potential!


Ever think you could use a 'local share bike' to cover 19 miles through 3 boroughs and over 3 bridges in a little over an hour?  Well, with ShareRoller you can.  Take a look at a recent ride below: Using the throttle heavily the entire time, and with some light pedaling, we averaged 15mph (including stopping for lights) and still had some range remaining when finished!



With all the battery power tucked inside ShareRoller's highly engineered case, it would be a shame to not be able to charge your phone or iPad.  So you can, anytime, and anywhere.  In fact, you could charge 50 iPhones without depleting the battery.  Bring on the next blackout!


Visibility is paramount to safety when cycling, especially in urban environments!  Forget to install or charge a light?  Not to worry, ShareRoller has super-bright front and rear lights for guaranteed visibility.  Great for share bike use too, as the existing lights on share bikes aren't always reliable.


ShareRoller uses friction drive to power the front wheel of your bike or scooter, and attaches to the bike in a most ingenious manner (so much so that we've filed patents on it!).  The secret is that ShareRoller slides on and mounts to a triangular mounting bracket above the front wheel of the bike (which just so happens to be exactly the same bracket already present on many share bikes).  Simultaneously, the motor assembly swings out of the case and locks into position to securely and efficiently drive the front wheel (also Patent Pending!).

It mounts in exactly the same fashion to a share bike as to a personal bike as to a kick scooter.  Our Universal and Custom adaptor mounts allow a perfect fit on almost any bike or scooter!

Then, you simply remove the throttle assembly from the case, clip it onto the handlebar (where it perfectly positions the variable throttle button for your thumb), and away you go.  It may sound complex, but the whole process literally takes about 5 seconds.  And it's just as fast and easy to remove it when you've arrived at your destination (which you will do rather more quickly than before!).

Friction drive is one of oldest and simplest technologies for an e-bike, and with our proprietary patterned urethane drive belt and variable pressure system, we've maximized the efficiency and effectiveness of this beautifully simple mechanism in all weather conditions.


ShareRoller's motor retraction system makes it incredibly compact when being transported, and keeps the motor safely concealed inside the case.

As a result, ShareRoller is less than half the size of any other portable, self-contained friction drive system.  And because we use the absolute state of the art in motors, batteries, and control systems, ShareRoller weighs less than half as much as well!

At 5.5 lbs and with an easy carrying handle, you won't mind carrying ShareRoller to and from the share bike racks or inside when you lock up your bike outside.  Particularly when you know ShareRoller will get you over the Brooklyn Bridge without pedaling!


Batteries:  Not all Lithium batteries are equal!  We use the very latest (and most expensive) Lithium battery chemistries for the highest power density, lowest weight, and greatest safety.  In fact, our extended range cells come from the same supplier that Tesla uses for their Model S!  And all battery packs are controlled by a sophisticated Battery Management System to maximize performance, longevity, and stability.

Motor & Motor Controller:  We use the most advanced Brushless DC (BLDC) motors on the market, with the highest quality magnets, windings, and bearings.  This maximizes power, minimizes weight and size, and provides superior durability.  Our state-of-the-art software-linked motor controller maximizes energy efficiency and even recharges the batteries when you coast downhill.

Microprocessor Control:  Every aspect of the ShareRoller is controlled by our custom proprietary PCB.  Our bespoke software constantly monitors throttle position, RPM, speed, voltage, current, power, and temperature to guarantee safe, efficient, and seamless performance.  You wouldn't want to know how many decisions per second are being made by the electronic brain, but all you see is the absolutely perfect operation it gives ShareRoller.

Mounting mechanism:  So innovative it's Patent Pending.  The critical breakthrough that allows ShareRoller to be attached or removed from a share bike in under 10 seconds.  It's taken a lot of creativity and a ton of engineering resources to perfect it, but as a result it works perfectly and effortlessly!

Retractable motor assembly:  Makes ShareRoller unbelievably compact when in transport.  The motor assembly swings in and out of the case in an elegant dance.  Unheard of in the world of portable friction drive systems (ok, it's a pretty small world).  Don't ask how many CAD design hours this required... which is why it's also Patent Pending.

Variable pressure system:  Spring-loaded expansion mechanism guarantees precise pressure on the bike tire, resulting in optimal performance, even in wet conditions.

Patterned urethane belt:  We've worked tirelessly with our urethane supplier to develop a proprietary motor belt that maximizes grip and efficiency in both wet and dry conditions.  Plus, it won't cause excess wear of the bicycle tire or scooter wheel.  That's pretty important.


ShareRoller possesses some impressive technical specs, with more power, higher speeds, longer ranges, and lighter weight than any other similar product on the market.  All of the figures below will be met or exceeded with production versions.
