Re: Holding your pants and your battery...

Local hardware stores usually have those ratchet straps. You can have them the first day. Shopped a few places, actually. Harbor Freight, Lowes, Home Depot, Ace, ... Couldn't find any of the smaller endless loop types at a store. They were all enormous and have hooks, or were a perfect size, but di...

Re: Holding your pants and your battery...

I've been using endless loop ratchet straps on my builds, since I transfer 2 batteries between 3 ebikes all the time. The ratchet is a little bulky, but very effective at getting anything attached to anything. https://endless-sphere.com/forums/viewtopic.php?f=6&t=102372 Got them on amazon prime : ht...

Re: YALU New BBS-Style mid drive kit with external controler

Okay, now this looks cool. It's like they took a cyclone motor and attached a bbshd style planetary to it. We def need to see what those gears look like. It also seems more serviceable than the bbshd, in terms of adding grease.

Re: Thread for new battery breakthrough PR releases

New anode tech: coat a porous silicon anode in alumina, then let the alumina saturate with lithium. It becomes a protective catalyst layer for the cathode, and keeps max capacity stable over 100's of cycles. So, not only do we get a decent jump in capacity, but cycle life as well. https://phys.org/n...

New little breakthrough in preventing oxygen release from reacting with electrolytes, involving a molten salt treatment to the Li-rich cathode.

Re: Huffy Mayhem | Cyclone 3000 | 14s 30a

Question for ya... how did you get the cyclone chain tight in that setup, as so you didn't need the idler pulley? Seems like you usually need to be able to move the motor up/down to get that I had the idler on when I first built it. But, my 14/44T motor -> crank gearing combo made a perfect, tight ...

Raleigh Route | BBSHD | 14s7p 35E

The number of ebikes one should own is always n+1. And, a bike with no motor on it is just waiting for one. Plus, I needed to build an alternative to my hi-racer bacchetta, which was my cardio ebike for a while. Problem is, the speeds I like to ride at make regular bumps cause a fair amount of lower...

Re: What are some good 3000W hub motors for 26 inch rims?

On a torque control throttle wheelies will only come when you want them, and you can directly adjust torque without affecting peak power by modifying the phase current limit. That does actually sound like a better option than voltage control. You won't have to deathgrip the throttle when going over...

Re: What are some good 3000W hub motors for 26 inch rims?

First off, does that sweet mtb have a 9mm QR , or a 12x142 thru axle? A 9mm QR with vertical dropouts is what you need, using two torque arms on each side. Be careful of going big on the phase amps on a 3000w motor. The frame will not like it at all, unless you engineer clamping dropouts like this b...

I would also strongly recommend you investigate alternate suppliers for the battery. This is the most expensive and shortest-lived component, quality and reliability are paramount.

If I had a low powered hub motor, where I can use all of the gears on a multi-speed cluster, then I'd opt for a cassette version, if available. I fried the DNP 11-34T 7spd FW on my fast hub motor bike (impossible to pedal on human power). I replaced it with this 12T single speed offset freewheel , a...
