for the 360watts the top speed i heard is only 32km/h Maximum (24v on a lifepo4 30hr) . being 32km/h is bit too slow, weak troque , never been so fun for me too !. Burtie is exactly right, bigger watts is the best choice. once you have fixed it with 900watts or 1200watts (3piece of crank kit). for other kits 1000watts 7tooth motor is not a good choice unless if you know how to switch it to a belt to run, ya - silent. if you are using the 7tooth gearing.. (please don't take out once you have fixed it) getting a lifepo4 will give you a good coverage range. The good thing about 24v 20hr lifepo4 is the cost is much cheaper, easily to replace if the battery is down. Also, the battery weight is much lighter and battery holder can be much easier to build.
higher watts kits 900above, best thing is the troque 0km/h to 40km/h can be done in few seconds. Actually cyclone intend to build Double motor 1200watts , seem unsuccessful. I think motor holder must have bend badly when it drag test. 0km - 60km/h in 3seconds. Faster then my 150cc honda bike. he got to come out something made of solid steel , that won't bend.
Conhis hub motor run on April 2010, 48v 1000watts hub motor distance run 5800km, and Re~alive cyclone kit bought in year 2009, Bought a greentime controller 18fets- 4110 , 48v~ 90v , 3-speed mode. Latest top speed I got for my greentime controller 76.8km/h ! , yet to reach 80km/h, or I will never reached 80km/h ?
