I am looking for some panniers that can double as a battery box for a rather large battery I'm building (14S 10P for 18650 or 8P for 21700). Hoping to keep the depth of the box as thin as possible (so around 3.5-4 inches) so they don't stick out too much. Since it is such a large battery I...

I am also doing a similar build but was wondering if this frame fit the BBSHD, does any one know if it will fit? Looks like they have the 02 in one of their frames on the site, but can't tell.

For future generations who find this on a google search: So on your advice for checking the chainline under load, I did notice that the bushings for the suspension were worn. I replaced them and that seemed to help a lot. Hopefully this makes it last a lot longer. Anyone know if a cush drive...

I usually hit the throttle once I get going, but the slipping/breaking happens really at any point during the ride. So I guess mashing the throttle? I was hoping there would be some parts to buy for a cush drive, or a standard part for bicycles. It seems that the only solutions are for...

I have a lekkie chainring in the front so the chainline is pretty good, particularly in gears 3 and 4 where it tends to skip first. What exactly is a cush drive? Google search doesn't turn up much. Is there a post to link to?

I've put about 2500 miles on my Ebike since converting it to the BBSHD and man-oh-man does this thing like to explode final drive parts. To date I have destroyed: Nexus IGH 3-speed (don't even bother with this, it blew up so fast) 2 Shimano CS-HG20-7 Cassettes (exploded 7th gear and broke...

This is a very real possibility actually, however I do not have another controller, is there a different way to test this?

I have a BMC motor that appears to be having some hall sensor problems. Motor makes very sad grinding noises when power is applied, but turns freely forwards and backwards with no power. I had probed the blue, yellow, and green wires while turning the motor backwards to see the voltage change...

Just to make it clear, I already did a disc brake conversion so that should take care of that. As for the hard cells, do you like them because they don't need any external casing or because they have lasted/performed to your expectations? What are your thoughts on a soft pack 6S from Turnigy in...

To add more information: Right now I am worried the full suspension frame won't fit the GNG motor too well since it requires a clamp to the frame while the drive pedals are on the moving suspension. If I do go hub motor, I was thinking about buying a new motor because I haven't been super...

I've been riding an electrified 48V hub-drive Hybrid-style commuter bike to work everyday for the past two years and I'm starting to seriously think about converting a mountain bike to make trail riding a blast. For motors I was hoping to reuse something I already have, but can be swayed to...

Amberwolf, thanks for the reply. You bring up a good point about stopping distance needed at 40 mph, the bike has upgraded brakes/tires, but I fear that the suspension/frame would not hold up. Perhaps the target of 35 mph, as suggested by drunkskunk, would be more appropriate. I have been...

Just to give an update: Just got off the phone with Jason from Ebikekit.com. It would appear that the motor is good up to 100V and the controller puts out 20A, he believes the motor can handle 2000W with little issue (not warrantied of course). The controller I have (the 72V upgrade no longer...

My trusty steed: It is currently powered by EbikeKit.com's direct drive motor (model they had in 2012) and their 'upgraded' 72V controller they offered back then. The battery is no longer the lead acid in the picture, but the straight-from-china special 48V 10aH lithium ion (as pictured...
