Try B- for hall ground instead of pin J1-4, the internal 511Ω may be the issue. I have this Curtis in an old dirtbike and use a Magura twist 5kΩ, safety is worth a few extra bucks. https://cart.electricscooterparts.com/magura-5k-ohm-twist-throttle-with-matching-grip I couldn’t get rid of a...

I've been building self-charging mountain ebikes for years. It's been a great way to stay cycling fit and generate power to charge batteries from 12-50v. I charge all my bikes with human power this way year round. Extra energy goes to a micro solar bank for my LED shop lights. Sorry for the...

The ebikes you don't have to plug in. Recharge by spinning and get a workout tracked with a powermeter. Charge any battery from 10-50v. Possibly the first multispeed regenerative braking mid drive ebike. Spawned from a steam engine generator project. https://makerfaire.com/maker/entry/66242/...

I'm bad with updates. Last year I did a double motor swap, putting the BBS02 from my Superlight on this bike since it was the better DH bike. The BBS is now a a third bike. There is great DH riding in my town. Backyard roadgap test, got a little close to the camera guy: https://youtu.be/HSYhW91KsNw

It's geared more for climbing than high speed but I'm guessing with 34-11 gearing and 2.5" knobbies maybe high 20's on flat ground? I built it mainly to climb this hill so I wouldn't have to shuttle or push: https://youtu.be/UQ1KUIcgYVY UQ1KUIcgYVY This is the steepest part on my local test...

Dauntless - this is probably the simplest form of 2d suspension, with fewer parts than a lot of current 1d designs. The swing link on the shock pivot is only for lateral stiffness, not part of the 2d system. We also have a two shock version (being updated) with a discrete link that is equally...

These guys might be worth a look for adjustable dropouts, we have used them for years - http://www.paragonmachineworks.com/cgi-bin/commerce.cgi?search=action&searchstart=18&category=0006

This is my solar DH bike and first ebike build. I made a lot of mistakes along the way, but it didn't cost much and I learned a ton. The frame is a 2012 Bicycle Fabrications MissingLink(TM), co-designed by Hank Matheson and I. Hank did most of the fabrication. You can see more on the MissingLink...

I am attempting to build a steam engine generator with an ebike motor. Steam is very challenging but building the engines is really fun. This is one I built from a 32cc chainsaw motor and Honda 50 valves - https://youtu.be/PXRsG6yDX_w

Thanks all for this forum. A little experiment I have been working on for years: https://youtu.be/9z9b6AC46Nc 9z9b6AC46Nc Progress was slow until I got the jackshaft idea from building ebikes. Probably breaking all kinds of rules but I am learning a lot. Made a new end plate for the motor, and...
