R12-a Electric Bike
You asked for it - so we built it. The R12-a is the same popular
R12 step-thru electric bike with an 8-speed derailleur. We also
added a new power control meter on the handle bar, upgraded
the grips and had the frame painted a deep blue.

Click here to see a video of the R12 in action. This has
been one of our most popular bikes and is on
special for a
limited time.

European styling makes this step-thru attractive and a popular
choice for commuting to work or the store. Large rear rack is
perfect for carrying books, groceries, or your picnic basket.

Front fork shocks cushion your ride. You can also add a
suspension seat post and cruiser saddle for added comfort.

The "R" series bikes are our top models designed to be
comfortable and long lasting. These are the finest electric bikes
we have ever offered and compare to electric bikes costing
more than twice as much.

The R12-a uses a patented bracket mount 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 bracket mount 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 R12-a has a V-type front and rear brakes. The smooth
shifting Shimano Acera derailleur is combined a an
SRAM cassette.

Quality components make the R12-a an easy and comfortable

Lithium batteries combined with the crank motor allow you to
travel farther.
