Re: $600 cad walmart build

I know nothing about that kind of motor installation, so how does it perform for you?...power, speed, etc.? Only other question is on the bike. Do you know if the rims are single or double walled, and what gauge are the spokes? Being new to the ebike deal, I'm being constantly amazed at the various ...

Re: Full suspension mountain bike Friction Drive

Wow!...lots of wizardry present in this thread. I'm a total greenhorn on the ebike venue, only recently exposed to them in the form of Trek and Specialized emtb models and my recently built BBSHD into my '08 Santa Cruz Nomad. I am not a greenhorn on bike mechanics, suspension technology, and decentl...

Re: Bafang BBSHD Stone dead - after replacing controller???

OP, it sounds like one of the sensors that will kill the motor is engaged somewhere in your system. If you're running your display, you have the main harness bundle connected to the motor. Brake sensors, shifter sensor, and the component in the case that kills the motor when back pedaling all kill t...

Re: E-bike mid-drive motors hardly outperforms hub motors

So many bike manufacturers are building with BB drives nowadays because of the low power legal limitations and the light-weight marketing in bicycle industry. They are making very good ebikes for the bicycle sport crowd, but very poor commuters that are high maintenance and low performance. Yes, it...

Re: Fitted a bbshd to a cheap fatbike FS frame..the result is dangerously hilarious.

I want to laugh and cry over that vid...LOL!...well, no crying...I'm not that torn up. Maybe this is like sticking a Kawasaki H2R 200hp engine into a Honda XR100 frame and expecting good results. At some point I thought maybe the guy was doing the sarcasm thing. On an actually serious note about the...

Re: BBSHD 29er or 26 or 27.5 FS Mountain / Off Road Opinions Needed

Which ever chainring you go with, just make sure you select one with a narrow/wide tooth profile. That and a clutched derailleur can cover quite a few sins on the old chainline.

Re: BBSHD 29er or 26 or 27.5 FS Mountain / Off Road Opinions Needed

geosped, on the chainring does the Lekkie have enough backspacing to provide a good chainline? The deepest Lekkie is about 20mm, while the deepest Luna is about 25mm. In the case of my Nomad pictured above, I couldn't get a good chainline except with the Luna 42T with a 25mm offset. Now, I'm not say...

Re: BBSHD 29er or 26 or 27.5 FS Mountain / Off Road Opinions Needed

geosped, that bike looks like a decent candidate for the BBSHD. On that chainguide at the BB area, do you have a closer pic of that? Even on single chainring setups that are so common today, you usually don't need chainguides with a good chainline and something like the Luna 42 Eclipse that has a na...

COAR, thanks for responding.

Re: Nm Torque Comparison to BBSHD

Modern wheel sizes run smaller chainrings so the torque is only reduced at the wheel on the higher side of the cassette. I spend most of my day on my non-ebike 29er in 1:1 or higher reduction part of the cassette. I disagree with looking at raw numbers, look first at weight then at how the motor an...

OP, I'm curious on that 70-120 Nm rating you mentioned for the factory emtb's. I'm no guru on ebikes, but I work part time as a mechanic at a shop that sells Trek, Specialized, and Santa Cruz. I've gotten to ride Trek and Specialized emtb's, and they are impressive. However, I thought their torque n...

Bafang Hydro Brake Switch Issue

I'm loving my BBSHD on my Santa Cruz Nomad MTB. I've had one issue that befuddles me that involves the hydraulic brake lever sensors. I don't see a lot on the forums about these sensors besides people having questions or issues about where/how to mount them. With only a little head scratching I was ...

Bafang 500C Display Question

I have a Bafang 500C display on an MTB with a BBSHD motor. My downloaded manual for this display appears to show a bar graph on the left side of the display for reading watts under the actual number readout for watts...much like the right hand side of the display showing voltage or charge percentage...

Re: DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

I'm a long time motorcycle rider and rode my BBSHD for over a year with the PAS disabled. Throttle only. It was very natural to me and even after fixing the PAS, I still go with throttle quite often for more precise control. Interestingly, I was recently stopped by a park ranger who asked me if my ...

Re: DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

The newer units appear to be shipped with the "fixed" firmware so it sounds like you got lucky and have the good firmware version. One trick I learned was if you want to cut the power instantly while using the PAS, just pedal backward. Otherwise the motor keeps going for a split second wh...

Re: BBSHD 29er or 26 or 27.5 FS Mountain / Off Road Opinions Needed

Strictly from my opinion and observations so far on the ebike front, I don't think there's much reason to have really light weight framed emtb's because there's not really much of a penalty to have a heavier, burlier framed pedal assist mountain bike. It may actually be a benefit to have the heavier...

Re: DIY Fix for BBS02/BBSHD Pedal/Throttle Issue
