Re: [EVDL] hub motor for 20" wheels

I have one (BikeE) laced radial on the non-drive side and it is fine. I was misremembering that it was radial on both sides. The drive side on both my BikeEs are 1 cross pattern and the one without radial lacing is 1 cross on both sides. It may be necessary to use a drill to angle the rim holes

I have seen very little evidence of such. Most people are still driving their conversions BMS or not. My vehicle has over 20,000 miles on it with no sign of capacity loss. Sent from my iPhone > On Aug 13, 2016, at 3:50 PM, Lee Hart wrote: > > paul dove via EV

The 42 x 60Ah thundesky pack in my vectrix was originally installed in 2010 It's done 105'000km, and around 1100 cycles equivalent capacity is down to 45Ah The e-rider's lack of BMS is likely what killed the first 4 cells For your application, the e-rider continuous discharge rate may be a

A tandem three wheeler like the Greenspeed. Low the the ground and good aero. First dam off the front with a good fairing then build a frame work to support the panels. At this point if it is stiff enough to resist the wind, ala the Elf,one might think about some sort of under cover and

[EVDL] semi off topic

Since David hasn't started playing whack-a-mole on this, I'll pretend that it is semi on topic. It seems reasonable to discuss the source of energy used to drive our EVs. I visited Las Vegas (for the first time) this past December. I was struck by two situations that offended my delicate

[EVDL] Which one china lifepo4 60 Ah?

Hi, I have china e-bike "Zapp" (www.erider.cn), 2,5 kW / 60V engine and 19s (40 Ah) LiFePO4, without BMS. Oryginal cells (from 2007) were made by Thundersky. After about a year of use, the 4 cells (from 19) were dead and I stop to use e-bike. Now I started to "repair" this e-bike. I order the
