Re: Build pack onto and around frame tube, rather than inside?

... and then wrap the entire pack in a self-fusing adhesive tape (which would also waterseal). Promising idea. The stretchiness and rebound of the tape should help keep the batteries tight to the frame tube down to mildly cool temperatures. Be aware there are several variations of quality and prope...

Re: Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

They both take 20" wheels, yet have brake bosses designed for 16". Excuse me if I'm missing something as it's been a while since I've messed around with cantilever rim brakes, but if the canti bosses on the forks are located for a 16" rim, how would you be able to get the pads to the...

Re: Can I and should I do this

The pedal drop is more like 2", since the bottom bracket is located about 60/40 between front and rear axles. You could put a 36 tooth front sprocket on and some shorter cranks. Are you sure the OP wants to keep the 26" on the front? Looked to me like OP wants to go 20" on both F/R: ...

Re: Hailong 03 down tube battery - how to attach it appropriately?

Add a few more rivet nuts (sometimes called "rivnuts") to the DT. Four should anchor it better than two, no? 5mm is standard but you could easily install 6mm. If you feel you lack the skills (check YT for adding rivnuts to bicycle frame) most good bicycle shops do this routinely, no big de...

Re: What are the best ways to build a two wheel hub mounts e-bike?

I remember seeing a Micah Toll youtube video explaining this a few years ago. Seemed rather simple. Two controllers, sharing one throttle IIRC. He was doing two wheel burnouts on the beach!

Wide tires can be had but is there room for them on your frame?
