Re: Bafang i thin I hate you... ( HALP ME!)

For every Bafang horror story, there are probably 100 others who are happily and reliably motoring along. If you're blowing up transmissions on 900cc sport bikes (and every other ICE bike you've owned), I assume you're pushing a little Bafang motor to its limits. If you're after crazy power, get a m...

Re: Cromotors Phantom X High End Parts

Is this stuff still for sale? Possibly as one big lot? Would make for a fun build. I've kicked around the idea of doing an e-bike/e-moto hybrid. Probably be signing my own death warrant, but it would be a rush.

Re: IT'S ALIVE...... BBS02HD!!

I will have to store this info away for future reference. I'm trusting the stock BBS02 to carry me everywhere I want to go. However, if I get the need for speed, I might have to give it a go. If you ever open the motor back up, be sure to snap some pics of the innards. This is the kind of stuff I lo...

Very nice! I may have to try this mod in the future. To clarify, one would need a BBSHD controller, motor core, and non-drive side cover. Correct? Have you been able to compare power consumption, efficiency, and performance? What is the advantage to this mod over just buying an HD? Just the better c...

Subscribed! I am a builder/developer in the oh-so-tiny off-road handcycling scene. E-assist has proven to be a game-changer. However, most of the DIY kits don't integrate too well into the available equipment. This kit looks like it has fantastic potential.

Re: Loving the ebike life but wishing for a full suspension bike...

When it comes to FS MTBs, I think the older stuff is better for e-bike conversion. Back around 2000, the downhill MTB scene was all about hucking long-travel bikes off of cliffs. Some seriously burly bikes were being produced. Since then, "standards" have changed about 20 times, so the older bikes a...

Re: Ok, I bent the new rim... Looking for a stronger rim.

What kind of bend did it suffer? Sidewall dented? Or, was the entire rim bent? If it's just the sidewall, I'd bend it back, true the wheel, and keep running it. What type of tire/tube are you running? Can you fit a little bigger tire in there? I'd run a Maxxis Hookworm with a thorn-resistant tube an...

Looks like a very cool drive! I just ordered a couple Bafang mid-drives, and part of me wishes I had waited.

With 96 pounds of water (12 gallons at 8 lbs per gal), I'd definitely put some thought into the kind of bike you'll be using for such an endeavor.

Re: BBSHD phase runner crank gear choice?

I think it largely depends on the rear wheel size and intended use of the bike. I've been under the impression that the 30T is usually the way to go for most off-road applications (especially if the tire is anything bigger than a standard 26"). If only riding on the road with smoother/smaller tires,...

Re: MAC 10T @ 36V vs 12T @ 48V??

The off-road handcycles commonly encounter terrain which requires one to move along very slowly. However, it's not necessarily a steep grade or something that would require a lot of power. Just plodding along using careful navigation so one doesn't flip over. However, I'm sure there will always be t...

Paul knows his shit a lot better than me, (em3ev). However, did you tell him 3 mph? That needs a mid drive, and a very very low gear. IMO, when you want to go that slow with a hubmotor, under a heavy uphill load, you will need the slowest rpm motor you can get, combined with the smallest wheel you ...

The link you gave to the handcycle shows a vehicle with 24" wheels and not 26" as you stated in your first post. A 12T MAC in a 20" wheel would fit perfectly. Just swap the shock for a slightly longer one if you want to return to the same ride hight. But I don't think the 2" lowering at the rear ax...
