The Sierra Trails is a step through frame design, battery powered electric bicycle, running on a 300 watt rear hub motor. The motor is completely sealed in the rear wheel and there are no moving parts visible to the rider. Made with all top of the line components this model includes a 7 Speed Shimano Tourney® Gears & Shifter System, 2 SLA E-Bike Batteries In A Sealed Pack, a 100% Steel Frame, fully Adjustable Seat, and 26 Inch wheels with Kenda brand tires. If non of this sounds appealing then notice the Batmobile inspired fenders.
There are 3 power options:
1. Twist the throttle and take off under electric power only.
2. Press the PAS button (Power Assist System) on the handlebar and the electric power will only kick in while you are pedaling.
3. Turn off the PAS system and simply pedal the bicycle like you would any other bicycle and ride with the power off. When you are ready for assistance, simply twist the right throttle grip and the power is there for you instantly.
The Sierra Trails Electric Bicycle will travel up to 20 MPH for approximately 20 miles on a single charge and takes up to 4 hours to re-charge (charger included).
It’s a great woman’s electric bicycle because you can step right through the frame instead of having to step over the cross bar, although, men often purchase the step through version as well. See the video here
