Re: Sur-Ron - New Mid drive Bike

I am also running M403's on both my Light Bees (with x controllers). After every 20 miles + trail rides, all four valve stems look like they are ready to rip off. I have been letting the air out, straighten them up and do it all over again. Tried running as high as 15 pounds and it didn't help (als...

what kind of derailleur and cassette did you end up getting with? does it matter to have bigger gears like 46/5x , 12 or 10 speed on this kind of bike ?

Re: Qulbix Q140MD - any experience?

looks awesome!

You can re-cell the packs with better cells, Sanyo GA cells have same performance as stock Panasonic PF but you get 37Ah instead of 32
how difficult to swap the cells ? are they all spot welded ?

Re: Sur-Ron - New Mid drive Bike

There is no doubt that those guys would be charging a lot more for the bike if they could. I don't agree. I think its at an impulse buy price. A nice toy price. It will fit on a credit card price. Raise it much and it is in a completely different category. Even raising it just from $3499 to $3,890 ...

Re: Sur-Ron - New Mid drive Bike

Looks like the X version is using a DNM bicycle rear shock. The current version seems to use a small pit bike / dirtbike shock. I think the current dirt bike shock is probably better than using a DNM bicyle shock because the bicycle shock was not designed for the heavier weight of a motorcycle whee...
