Re: Sur-Ron - New Mid drive Bike

...The sur-ron engineers probably put a lot of thought into the bike and the geometry and handling. From downhill racers, it seems you can really mess up the handling of the bike by changing things just a few degrees. You are *far* more optimistic about how much "thought" chinese engineers' put int...

Re: Sur-Ron - New Mid drive Bike

What I don't get is you guys who ride in areas where you can legally ride dirt bikes. You also ride in areas which really would be better with a bigger bike and the suspension, I would assume, since I have not rode a larger bike, a larger bike would be better in those situations. Why would you not ...

Re: Sur-Ron - New Mid drive Bike

I'm continually seduced by the prospect of getting one of these.... but.... The tires look skinny to me seeing as I ride in a lot of deep sand and gravel washes... perhaps if they are aired down enough it might be passable... Anyone riding these in deep sand? How much of a handful are they in the de...

No need to do that, I ran the Tubliss system on KTM XCF450, even flat, whacking the throttle and dumping the clutch, the tire didn't slip on the bead. No need for rimlock.
Tubliss system is a rimlock

Re: Frey FAT 1000 2.0 first impressions

I've got about 10km on the bike and 4km on this chain and it's showing very little stretch, maybe a bit less than 1mm when I checked a few weeks ago The early tunes I was running were harder on things including the drive line and battery life but even when I didn't maintain the chain at all (I did a...

...If you change the chain every 1000km that ain't to bad. With a hub motor though the chain isn't affected as much, maybe it requires less maintenance.It is harder to take out the rear wheel though ;) I ride hard on a fat tire (presently 26x4.8") bike with a BBSHD and after getting the tune figger...

Re: Sur-Ron - New Mid drive Bike

These bikes can have the chain semi tight with very minimal slack and should be adjusted that way. Unlike motorcycles, there is no change in the secondary drive chain tension when the suspension is compressed or extended unlike motorcycles, because the pivot shares the same location as the secondar...

I readjusted to a looser tension,just a little give in the chain now.Its a little cooler and less noisy .
A chain shouldn't be even close to tight - should have plenty of play

Why not the entire bike which would...

Re: Preventing BBSHD Removal

No matter how good your lock is, it will almost certainly take less time to defeat it (I'd guess no more than five or six minutes with a portable angle grinder) than to remove the BBSHD

Re: Preventing BBSHD Removal

Seems to me if folks have the time and determination to remove a BBSHD from a frame, one can succeed no matter what anti-removal prevention measures or they'll just take the whole bike... I don't really get the concern

Re: Reliability - Are there numbers?

BBSHD on fat-bike at ~10,000km with plenty of off-road - only service to motor unit was teardown, inspect & grease at ~1000km

I get >3000km on 11sp chains, cassettes and chain rings
