Re: Sur-Ron - New Mid drive Bike

I have never had problems with lifting up the wheel with 52T at low speed. Especially easy off road! The stock 48T is not fun at all, I admit. New X controller, "V2" is sick! 90DC Amps and 450Phase. The difference is really there. And when I drop in the 13p 30Q battery the bike is really ...

Re: Sur-Ron - Belt upgrade KIT

belt 100% straight in line on the front and rear pulley.

under 100Hz same problem.

130Hz noise it gone but you veel there is something not good and to much tension.

I think this is the rear pulley thats not flat/straight, how can we fix this problem Allex?

Re: Sur-Ron - Belt upgrade KIT

the noise always come back after a while. there is only one thing left that can be wrong...the offset from the pulleys is not good. I,am stil sure the hubs are 100% fixed duty/specialy the smal front pulley, the pulleys are crewed on to the hubs so the pulleys also must be 100% straight. Front and r...

Re: Sur-Ron - Belt upgrade KIT

I re-ligne the wheel one more time. Cant see any problem: al these parts are fixed(zero play on the bearings)...you can line the rear hub in the swingarm and that is it. Marks on the swingarm left side and right side the same...then hub must be 100% straight in line so the pulley that is fixed on th...

Re: Sur-Ron - Belt upgrade KIT

Looks good, although it is recommended to check the tension on the below part of the belt. What tyres do you use? So you never added grease on the actual teeth but rather on the high side of them - the outer side where the flange of the big pulley is? Interesting. I try to adjust the belt so it bar...

Re: Sur-Ron - Belt upgrade KIT

Put small amount natural grease to the outer side of the belt and the squeak is gone, so the problem in not in the teeth section of the belt but more on the side. The Hz i have now on the gates app is 80Hz 86Hz 90Hz 83Hz turnt the belt and measured in 4 places. Run the bike yesterday from a 100% ch...

Re: Sur-Ron - Belt upgrade KIT

Make no changes to the alignment are the tension. Water helpt to track down the problem for a part. Just a fingertip natural grease to the side of the belt/pulley edge and the beep sound under load and hi speed was disappeared.....but for how long????????? belt tension check video https://www.youtub...

Check al these things and the wheel is 100% in line and well fixed , after a long run stil the same in the marks. look like the big pulley is not strong/wide enough for the instant torque, big pulley have a bigger diameter and aluminium bends on top to one side under load...squeak noise where the be...

Re: Sur-Ron - Belt upgrade KIT

To assemble the belt drive kit takes 1 hour wurk for a practiced person. Easy fit and wurks perfect, makes the sur-ron a total other machine for me. Mine does 86-98Hz on the Gates App and i think the belt is already pretty tight! the noise is almost gone above 40kmh , with helmet i cant hear any noi...

Re: trouble sourcing a 7s bms

How much Amps is going to take maximum from the battery ?

For example:as the consumer takes maximum 15A , then is a 7S Li-ion bms with a max peak disharge from 20/25Amp okey :thumb:

as the consumer realy takes the 80+Amps the search for a fitting bms become difficult for 7S .

Re: Sur-Ron - Belt upgrade KIT

No need to think the gates belts wil be a problem for the first 20.000km
zero motorbikes and more big powerfull e-motors use a belt so why think this belt on a 5kw peak power sur-ron
wil brake? the carbon gates belts are made for this and they wear out you just swap a new one on in a few hours
