Re: sunthing28 ebay seller screwed me and wont answer my mes

of all types of batteries why don't choose hobbyking cells? pay the extra cost saving all the head burden. haven't you read up number of aricles some bms kills the cells. so, 1 proper choice choose:- lipos. even if your charger can survive a long time, i doubt the bms will service you a long time. c...

Re: 48v 500W vs 48 1000W Rear Motor

my suggest buy only 1000w hub motor. there is a big difference btw 500w. 500w hub motor i have seen it will heat up faster at 48v 1000w controller. if you are using 48v 1000w with the same controller or higher amps says 42amps/ 45amps controller the motor heat are lower. i have been using this 48v 1...

Re: any suggestion for e bike kit for KOREA?

either you choose hub or non hub motors. you need tools to fix them . you will need to change wheels to hub motors wheels and also do abit or alot modify the troque arm/plates. there is one way no tools require is buying a pre assamble ebike comes with warranty.

Re: Lyen controller problems with geared motor

the simplest is to run a controller without any programming. Try greentime . they have 48v, 60v or 96v type of controller. you can also try Huatong as well. as for the cost + with shipping to your house wont be expensive , it save your pocket. I have been running my greentime controller few years ba...

Re: Planning to buy 48v 6000w

yes, you are exactly right. the weight is at the rear . it could be this fork is too high. I have changed my rim from a thin spokes to a 6 spokes which is slightly heavier. it does help a lot.

Re: Planning to buy 48v 6000w

how fast you wish to clock a speed ? say how many seconds you wish to reach a certain speed? my suggest if you are looking speed below 50km/h, I will say that small motor of 500w will be sufficient enough to clock, you can always go a bit faster 55km/h. bigger batter and cells cost more always, I ha...

half twist throttle ? or a full twist throttle ?

Re: 1000watt ebay hub motor

your bike isnt a bicycle. so it will need to run from a dead stop.all these hub motor are more suitable to reach a better speed for 12cell can hit easy 50kmh on a typical. if you try to test your hub motor fitting into typical/ normal 2 wheel bicycle im sure you will get a higher speed.
