After testing many etrikes, the TK1 stood out to us for its stability. It just corners much better than others in its class. The trike can easily zip up to 16mph by pedaling or using the thorttle. However, beaware the first PAS level (electronic gear) is a little quick on the start. So if your looking for a slow easy go take off, this isn't it. Consider the TK Pro instead. The TK1 is powerful in a small folding design. 

The Mooncool TK Fat Tire has a larger wire basket on the rear. Due to the fat tires, its slightly less stable than the TK1 and TK Pro. But if you have good balance, it can easily be ridden safely. It has good power and good size battery to get you down the trail or across town. Its fun to ride and we sure enjoyed our time with it.
