Re: Best way to repair my steel torque arm

I have no idea where to find these part. I don't know where to go for scrap yard. I think I'll stick to buying online.

Re: Best way to repair my steel torque arm

Not Cromoly bolts, just grade 8.8 or higher standard metric bolts. 8.8 is equal to grade 5 is standard sizes, 10.9 is equal to grade 8 in American standard. 4130 is the USA standard, and common all over the english speaking world, but the European standard for the same steel is called 25CrMo4.

thanks guys. I just wonder where to buy chromoly. It's easy to get Stainless or Mild steel. But stainless is such a pain to drill I decided to use mild steel....

Thicker steel. Part of why I used a thick angle iron to make a similar TA. So there would be some meat on both sides of the holes I drilled. 25x25x5mm mild steel bracket ok? https://www.ebay.co.uk/itm/Mild-Steel-Angle-Equal-Unequal-Various-Sizes-Lengths-Angle-Iron/291739479215?var=590761552991 I ca...

The damage is from insufficient material. Why not making them better, either bigger or using better material.

Welding more material on a broken part is ugly, temporary repair.
What better material should it be?

I've used it to charge my bike overnight or to charge at work with absolute silence. It's charges slowly but it's much better for battery longevity that's why I bought it.

I opened the box just in case and found it it's only the speedict and without the wiring. It was sent back to me as repair but since then I used another BMS so never got to use it

Re: Speedict neptune lite (BMS) + Cell-log 8

What size battery is the Neptune for? Do you have the adapters for 13S? Sent from my moto g(6) plus using Tapatalk It works for any battery size. I don't have an adapter for the 13s but you can just solder the wire in, it's much simpler. Bear in mind it doesn't have current control, it's just readi...

Re: "Edge" DD hubmotor, 1500W, 35mm, Al core

Ok thanks. It's normal regen only then? No variable regen? (1 throttle for acceleration and 1 for regen) and only sensored but not sensorless?

I'll stick with my phaserunner for now then lol

Re: 416 Open Frame Power Pack kit

Yes.. this is cater more towards powerwall or external power pack. For ebike, unless it is a common model, the shape is the same. There's too many variation in size or shape.. is hard to justify which one to go. If space is not a issue, this maybe able to reconfigure to your need. I'm not talking a...
