I built a Lunacycle/Bafang BBSHD a few years back. The crank arms and pedals did exactly what you've detailed on the first trip across town. I rode home on throttle only with one pedal arm. Bafang aluminum was too soft for anyone larger than child size.
Similar problem: I'm a Clydesdale. ;)...
I guess that depends on the number and size of hills. I've helped with a DD setup and it didn't like low RPMs aka slow on a hill. Got really hot.
I can see why the BBSHD would seem risky - lots of moving parts vs none in the DD.
Interesting project. I want to hear how it goes.
I have 2500 miles on my BBHD. No electrical problems.
Did break a tooth off of the pinion shaft but that was abuse. The motor tended to loosen up and I've let tons of people ride my bike. I'm pretty sure everyone mashing the throttle hard from a standstill (like a motorcycle) and causing that...
I hate that thrill seeker speed demons are lumped together with the 5-10 mph trail riders like me. I'm not making any noise, not scaring anyone, never losing contact with the ground but somehow we're lumped in with the dare devils. Ugh!
I think a BBSHD motor setup would get the job done. Mine doesn't get hot as long as I keep the revs up. I live in a hilly place so I'm not aiming at 40 mph, I'm riding at 20 mph. I've had it up to nearly 40 mph but being a hard tail it gets pretty busy if the road isn't really smooth.
The...
Thank you.
Any links you can share would be nice. Measuring the old shell is difficult b/c once the new one arrived - like a dunce - I recycled the old shell. :shock:
I dived deep yesterday on the web and finally started noticing suppliers that had this kind description in their product...
Hello folks.
I'm working to replace the case on my silverfish battery that was damaged. The battery itself is fine, just needs a new exterior.
This is the bike:

Its been a good bike for around town as a basic commuter. Not really a mtn bike...
I'd like to have useful bike paths. In order to justify the bike paths here it takes alot of bikes who want to use a path. If ebikes are a growing thing then I expect the gov't to get involved after some clown hurts himself or someone else with a 10HP bicycle rocket used in traffic or on a...
I can tell you that I won't be "car sharing" any car that I buy. Dang, I hardly like offering rides to people. Do you remember the school bus way back when? People cut the seats, drew on the seats, tossed trash into the floor, etc.
I've given rides to well adjusted people over the years who...
I used my 90 degree air grinder (~$15 at HF) with a 2" Scotchbrite pad to remove the paint on the BBSHD shaft.
Loctitie would not stick to the paint. The paint was wearing off bit by bit and letting the crank arm get loose. I THINK I finally have it fixed. Am running Schlumpf crank arms. While...
FWIW It looks like I can use the BaFang config tool in free Mint Linux (Cinnamon and KDE desktops) with the free Wine emulator.
Will check soon - am waiting on a replacement battery charger.
That allows me to run my old netbook that someone gave me without looking for a Windows machine to...
