Re: DD Hub as a mid drive motor pros and cons?

by Chalo » Dec 27 2020 3:23am "If it were me, I'd make a plate with the 44mm 6 bolt pattern to fit the disc rotor interface, and a 74mm or 110mm 5 bolt pattern to fit any one of a number of chainrings. 74mm for rings under 34t, or 110mm for rings from 34t up. It would be easy enough to get it ...

Re: DD Hub as a mid drive motor pros and cons?

The problem with moto front sprockets is that the largest bore is 20mm and its splined.
Drilling out the hardened steel is a challenge.
Rear sprockets usually have a too large bore for the 44mm disc rotor hole diameter.

So custom is probably the only option.

Re: DD Hub as a mid drive motor pros and cons?

Is there an off the shelf sprocket that can mounted to the 6 bolt disc rotor holes? Or are the guys building these mid drives customizing motorcycle sprockets to fit on the hub side cover?

Re: New 80 volt push mowers

Has anyone got these batteries figured out? Mine was working fine I I think I reversed the connection to my mower and blew the fuse. I was able to replace the fuse and it shows 78v now but it won't charge. Charger light doesn't come on at all but the battery meter lights up as usual. Same result on ...

A customer returned this charger I sold them, claiming it overheated and melted the wires. I opened the case and it looks flawless inside. Is it me or do these wires look like they were cut?

A123 and Headway LiFePo4 pack, 72v (USA, central TX)

I'm looking to see if anyone is interested in this heavily used, 9 year old battery. It's two packs in series. Main pack is 16s A123 26650 cells, it's 4p, but only gets about 4ah (from the original 9.2ah). It has a bms. Was made by Paul at EM3EV back in 2011. Additional 7s Headway high power pack, s...

I'm trying to find distributors (not retail sales) for small ev related parts. I've spent a lot of time searching online and I really can't find much other than retail, and of course buying directly from the manufacturer (which doesn't help my current situation). When I search wholesale distributors...

Re: Non-China built chargers?

It's just simple ~36v 2amp model.
The current issue with China is the tariffs and delayed lead time due to factories playing catch up after being shut down.

Non-China built chargers?

I'm looking for a low power charger that is not manufactured in China. The ones in the US are pretty much all high end and not for the small ev market (no surprises there).
It doesn't need to be made in the US but I'm trying to stay away from China.
Thanks,

Re: Anyone use fairings? Why not...?

Hey stateofstatic... thanks for that post. i'm impressed that even the ATB-ZZ ( one of the most least aerodynamic looking of their designs ) does so well. -6mph at 45mph turns a ~3000w load into a <2000w load at that speed. Or allows you to perhaps hit 50mph on the same power. You'd think it would ...
