Walter Steiner
Nice bike for the price. Has all the features I want

Suspension makes a big difference in ride quality. Needed to search the web for the programming of the controller. Seat is okay, I replaced mine with a wider seat. First gear jumping between gears is a problem and needs adjustment. My biggest complaint is that the peddle crank arms are about 155mm which is a little short. I would prefer 175mm cranks. Top speed (locked) is 20mph so it's fast. Speed at level 1 is 7.3mph which is a bit fast then 3mph more for each higher level (5 levels). Doesn't seem to be a way to reduce level 1 speed except by using the throttle with no peddaling. I have not driven it enough to comment on the battery but so far it seems like it will last a good while. Oh yeah, looks pretty cool too.
