Optibike R15C Removable Battery

After 18 months of design and development this new wonder bike is almost 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 for 20 years. There is no other bike in the world with all the features and performance of the new R15C.

This ebike uses all the best components, this ensures 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. This is a testament to the quality of Optibike.

The R15C now has an ultra high capacity removable battery, which give quick access to all 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 165mm 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 Carbon Fiber handlebars, DT Swiss Rims and more.

Fox EBike Specific Suspension

The bike has the new Fox E Bike Specific 36mm Fork with the Fox Float DPX2 shock with EVOL. Total rear travel is 165mm 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 is the highest performing, longest range bike Optibike has ever made”

“We put every design detail we learned in the last 20 years of building electric bikes in to the R15C”

27.5″ Wheels

The R15C now has 27.5 inch wheels for better handling and reduced rolling resistance. The tires and rims are wider too for better traction.

Adjustable Head Tube Angle

The head table angle can be changed form 63.5 to 66.5 using the Cane Creek Angle Set head set. It comes stock at 65 degrees which is a good angle for combining stability and steering.

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.


More power gives you a higher top speed, and lets you climb hills faster.

Battery Capacity

A bigger battery means you can ride farther, it's like the fuel tank on a car.

More torque lets you start from a dead stop easier, and lets you climb very steep hills.

Some basics on battery capacity and what it means for 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 capacity 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.

A note on e-bike range:

There is no standard for E-Bike range like there is from the EPA for Car mileage/MPG, as a result of that an electric bicycle manufacturer can pretty much claim whatever they like for their range and top speed.

Our ranges are based on our actual usage and testing of the bikes, as well as feedback from our customers.
