An Electric Mountain Bike built for High Performance and Long Range
After 18 months of design and development this new wonder bike is here.
The R15C is a combination of everything we have learned in the last 20 years of designing and building electric bikes and racing motocross. There is no other ebike in the world with the features and performance of the new R15C.
It is the fastest electric bike we have ever made, with a top speed of 36MPH and hill climbing ability that is unmatched in the ebike world.
Designed as the ultimate electric mountain bike that can handle any offroad terrain, it’s also perfectly at home on the roads for those weekend cruises, commuting to work, or just going into town.
This e mountain bike uses all the best components, ensuring the bike will continue the legendary durability of the Optibike R Series. Most of the Optibikes manufactured in 2008 are still on the road today and are a testament to their quality.
The R15C has an ultra high capacity 1600Wh removable battery which gives it a range of up to 180 miles per charge (220lb rider with moderate pedaling), the removable battery also gives quick access to the wiring and controller. Maintenance is simplified as all components can be removed in less than 15 minutes.
Elegant Carbon Fiber Frame
The elegant flowing lines of the new R15C frame seamlessly integrates the high power motor and long distance battery into a high performance work of art. With a full 160mm of suspension travel in front and 220mm on the rear.
Highest Quality Components
The R15C continues the tradition of only using the highest quality performance components, like Fox Suspension, SRAM Code Brakes, Rohloff Internal Gear Hub, Renthal Handlebars, DT Swiss Rims and more.

We put every design detail we learned in the last 20 years of building electric bikes into the R15C
Suspension for Any Terrain
The R15C has a Fox Factory 36mm Fork on the front, with a Cane Creek DBcoil CS Shock in the rear. Total rear travel is 220mm and the travel is very progressive due to the motocross style linkage on the swingarm.
Fox Dropper Seat Post
There is a Fox Factory Dropper Seat Post so you can change seat height on the fly.
The R15C now has 27.5 inch wheels for better handling and reduced rolling resistance. The tires and rims are wider for better traction.
Low Frame Stand Over
The bike features a very low 28 inch stand over so it easy to get off and on and fits a large range of riders.
Compare to other Optibike Models
More power gives you a higher top speed, and lets you climb hills faster.
A bigger battery means you can ride farther, it's like the fuel tank on a car.
Battery Capacity and Range
A battery with more capacity generally means you can go farther on a charge.
However at maximum speed, a more powerful bike will also use more battery per mile traveled. Knobbier tires can also reduce range due to more rolling resistance on the road, and the terrain you ride on can also heavily affect the range you get.
At Optibike our ranges are based on actual usage and testing, as well as feedback from our customers.
There is no standard for E-Bike range like there is from the EPA for a cars fuel economy, as a result an electric bicycle manufacturer can claim whatever they like for their range and top speed. At Optibike we try to present estimated ranges and speeds that are as close as possible to what you’ll actually get.
