Let me try to simplify the thread/question as much as possible... If I'm going 25 mph and run over a bumpy patch of uneven pavement while my ass is on the seat, how much smoother and more comfortable will it feel on a "nice" FS bike vs a "cheap" FS bike? :)

If I decided to go with a nice bike with disc brakes (either mechanical or hydraulic) but I stick with a disc-brake-compatible hub motor (such as a Crystalyte H3540), is there anything in particular I'd need to watch out for to make sure it would work with a given bike? Having never done a...

No, pretty flat round these parts. After a bit more reading, you've got me thinking those BBSHD videos by "Bruno" got me expecting a higher top speed than it can actually deliver. I guess I'm still a bit torn/undecided between hub and mid-drive, especially since I've never owned or ridden a...

Hi All. Looking for some opinions.... I'm planning to do a new ebike build with a a BBSHD kit and a (not-yet-chosen) full-suspension bike, and I'm wondering if it'd be worth the extra money to buy a "nice"/”premium” bike with nice suspension components and brakes for maybe $1000-$2000 vs a...

PeterT12, I'd concur with pretty much everything in your post. Sorry to have worried you with my initial misimpressions. Yeah, that space is for a controller, which I got in my battery. The problem for me was that space for the controller is so long that it pushes the mounting holes too far...

The problem is the opposite. It's too far down and hits the seat tube. This hadn't occurred to me. Sounds like this is a pretty easy thing for a local bike shop to do? If so, it might be worth doing, as it would resolve my water infiltration concerns.

Thanks for all of the suggestions. I finally did file a dispute against BMSBattery with PayPal, and that was enough to prod them to finally communicate with me through email. And it turned out that there was a solution to my main problem of the battery pack not mounting securely to the frame...

I just updated my original post on this thread with new pertinent information that puts the Case-08 battery in a significantly better light. You can read it above, but I'll also copy/paste the text here. (See above for the photos.)

UPDATE (9-29-15): Turns out that the Case-08 battery case design isn't nearly as bad as I had originally posted... After weeks of BMSBattery refusing to talk to me at all about my problems or my desire to return my Case-08 battery (due to the issues mentioned in the original post, below), I...

Yes. I had the screws tightened as tight as I felt I could without risking cracking the plastic underneath the screw head. So pretty tight. I thought about that. But since this install was essentially a gift for my Dad, I didn't want it to look like crap. Plus using tie straps or hose...

The issue is that (in my personal/professional assessment as a mechanical engineer) the design of the plastic mounting bracket is deficient to the extent that I'm fairly certain that the mounting bracket will break after a relatively short period of use. And even if the bracket doesn't break...

I think I can hear some people snickering already. :wink: Yes, I rolled the dice on ordering a battery pack + controller from BMSBattery and got burned. I tried one of their new "Case-08" frame-mounted battery packs, principally due to the enticingly low-profile shape of the case, but it...

I built my Dad an ebike with a BMC V1 motor running on a 36V 25A 6FET controller, and its clutch seized up during a ride. (The controller also fried.) So now I’m trying to decide how to proceed to repair the motor. Here are my thoughts: 1. Purchase a new BMC V4 clutch assembly from EbikesSF...

So, this is kind of a weird question, but does anyone know if Brian is still around / alive / not-in-a-coma? The BMC V1 motor that I put on my Dad's bike last year is messed up and I've tried emailing and calling Brian numerous times in the last 6 weeks for troubleshooting tips with no reply. :?

Update: The local police put out a press release this morning announcing the arrest of the guy they believe stole my dad's bike, plus another separate guy, both caught in the act of stealing bikes last week. The guy who stole my dad's bike was caught cutting a lock with bolt cutters in the...
