Re: Giant Trance 4 XC 4000W Crystalyte HS3540

Going to put up a video in a few days. Still getting use to the torque and power of this Crystalyte, definately a huge jump in power compared to the yescomusa motor.

Re: Giant Trance 4 XC 4000W Crystalyte HS3540

Yeah I noticed that theres a dead spot at only when I start to twist. I already set the min voltage input lower so the throttle responds sooner

I'm still using the Cali-bike battery on my girlfriend's bike. Since its a 48v battery it tops out around 32mph fully charged to about 28-30mph.

Re: Giant Trance 4 XC 4000W Crystalyte HS3540

New rear tire, Schwalbe Big Apple 26x2.35. I am considering switching the front for a Schwalbe Marathon Plus 26x2.0 to improve the steering response. http://i553.photobucket.com/albums/jj396/evolutiongts/evolutiongts005/df900185-d384-4408-9fa8-e806bffac555_zpse71217e8.jpg http://i553.photobucket.com...

Alex DM24 in the front, and the stock Yescomusa rim in the rear. Changing to a Crystalyte Motor, stock wheel.

Re: Just got my ebike kit from yescomusa what battery?

Currently running a CST cyclops 26x2.4 up front with thick tube and Schwalbe Marathon Plus 26x2.0 with tire liner and thick tube in the rear. The stock rim is very narrow, the largest tire I was able to fit on the stock rim is 26x2.1, I would personally swap the CST cyclops to the rear, because ther...

Re: How far can you mod a Yescomusa DD HUb?

40mph with the stock rim and spokes but after 4 months of riding the spokes are getting loose and the wheel untrue. Still runs smoothly at high speed but I will be switching to a crystalyte motor shortly.

Re: How far can you mod a Yescomusa DD HUb?

I have the side covers drilled and vented, and the I only burst up to 3600w for a few seconds, maybe up to a minute before backing off the throttle, the motor barely gets warm. I'm using a $50 greentime 15fet controller. I admit my riding in the video is a bit ridiculous, and unsafe. Its not safe to...

Re: Just got my ebike kit from yescomusa what battery?

Are you running stock phase wires on the Yescomusa motor or have you upgraded those? And how about cooling? Still running stock phase wires, but since I'm switching to a crystalyte motor soon that one is going to have thick wires and huge cooling holes. On my yescomusa motor just have vented coolin...

Re: Just got my ebike kit from yescomusa what battery?

Greentime controller is great especially for $50, plenty of features most I don't even use. It has regen make sure when you order you specify the low voltage cutoff otherwise regen won't work. Shunt mod is easy just open up the controller the shunt is a upside down u. Just add solder to it and you w...

Re: Just got my ebike kit from yescomusa what battery?

Still on yescomusa motor but I upgraded to a 15fet 72v Greentime controller $49.95 off Aliexpress, works perfectly. Pulling 48Amps today with the shunt mod, full throttle got to 40mph+ very quickly and out accelerated 3 lanes of cars up to 41.3mph. Most of the time I wasn't even going full throttle,...
