The mini folding bike is our 16" (305) wheel model. Available with a 8 speed Sturmey Archer internal hub. The Sturmey Archer model has no external shifter (aka rear derailleur), no gears (aka cogs). Never worry about improper shifting or cleaning your drivetrain. It is all enclosed in a completely sealed maintenance free environment. Very comfy due to rear suspension design.
- 30 day satisfaction guarantee and 1 year warranty!
- 1 year bicycle warranty.
- FREE consultation for customers requiring assistance in getting bike into
optimum condition (brake, derailleur adjustment, etc.). After purchase place the shifter in 4th gear and align the two yellow arrows by adjusting the cable tension (very very quick).

All buyers should get their bike checked by a professional after receipt just
to be safe. Normally the brakes may be a bit off center, which is easy to fix,
the shifting will almost always be out, and the crank
bolts should be tightened. We will give free consulting via email and Instant
messenger (AIM DowntubeY) and phone 215-245-4032 to make sure all bikes are
set up perfectly for our customers. Ideally one wants a 35 degree knee bend
at the bottom of the pedal stroke. Arms should be loose and relaxed, and the
saddle angle should be level or slightly downward sloping......whatever is most
comfortable for the rider.
