I sent the company an email asking if I can purchase an extra battery so I can swap out the depleted one during a ride.R Martin wrote:Powerful mountain bike style electric bicycle from R Martin.
The "R" series bikes are our top models designed to be comfortable and long lasting.
The R10 uses a patented crank motor design. This design allows us to get more climbing power with lower battery usage. This also allows for easy changing and removal of both the front and rear wheels.
The crank motor enables the bikes gears to be used with the motor. This allows you to downshift for hills and to shift up to higher gears as you gain speed. This feature is exclusive to our "R" models.
The R10 is built with full suspension and disk brakes. Quality components make the R10 easy to ride.
Lithium batteries combined with the low power consumption of the crank motor allow you to travel farther.
A 36 volt, 8 amp hour lithium battery pack provides plenty of power for even the toughest hills.
Range is 25+ miles.
