GEBE'S website
Here is why that I think that this company GEBE has the best motored bike kit on the market.
Go over to their page and read the customer reviews. There are dozens and quite a few of them are mounted on to cheap Walmart bikes. I am a huge hater of cheap Walmart bikes and the notion of powering one of these things to 30 mph out on the road just made me go wild. But what I discovered instead of these poor quality bikes breaking they seemed to be fine under GEBE power assist. That led me to change my opinion quite reluctantly about these bikes and motorizing them! Many folks find them selves up against it with gas at over three bucks now! Mounting of this kit on one of these cheap bikes shows how gentle the belt drive and the drive ring is to the bicycle frame. I simply do not understand what is going on with that when I have seen strong riders simply tear these bikes apart pedaling them! I am not an engineer and simply have no answer for this fact but fact it is. That was another reason that I choose GEBE. If a Walmart bike can handle it what could my classic Fisher CR-7 do with this kit? I have that answer now with over 1900 miles on this kit.
The words are awesome technology!

While an engine provides more power than a person can sustain, it does so more smoothly. The maximum torque provided by the motor, even when geared down (and the torque geared up) to the 300-400 RPM at the rear wheel, is in the 25-30 foot-pound range.
A rider, on the other hand, when standing on the pedals and accelerating, can easily provide 100 foot-pounds at the pedals, and depending on the gear, nearly that much at the rear axle. The issue is that it's pulses of high torque that lead to failure, not steady low-torque.
High speeds DO come into play with the cheap bearings, spokes, and brake components on the Wally-World specials, though... Bearings fail early, as do the spokes.
