Re: OBREA GAIN D40 (e-bike)

Re: Front Hub Motor Not Working

The clutch mech inside can stick and is usually activated by 3 pins/springs found on the opposite side /face to the nylon gears. It could be that they may be oxidised as well and the springs if weak may need replacing. Link to pic. https://www.bing.com/images/search?view=detailV2&ccid=2kGR9TVP&a...

Re: Any Point Me Going Tubeless

Co2 is not recommended as a air source with sealants due to sealant reaction.

Re: Any Point Me Going Tubeless

I set up my Arkose as TL to rid my self of pinch flats. Arkose came with TL ready rims but not TL tyres so will buy TL ready tyres when replacement is needed, current tyres leech through walls a little so looses pressure when left standing after a few days. Choice of sealant after looking at reviews...

Re: What is the lowest battery ah I can have with 750w Bafang mid drive ?

As regard to your main question depends on how far and terrain you want to ride. The lowest ah you could run with would be 5ah - 7ah with v.good 15 or 20a rated cells but distance would be hampered most likely about 10 -12 miles, this would be a bespoke 26 cell battery would work instead of the more...

Re: What is the lowest battery ah I can have with 750w Bafang mid drive ?

You need to supply a link so we can see the battery and the full specs. Cells used will be 2500mah capacity and 13s 4p configuration to give 48v 10ah/480wh. The real detail needed is the actual cells used inside, make and specific name of cell used. 750W BBS is a high performance mid drive and needs...

Re: New e bike conversion PAS knowledge needed

It depends on the controller software/programming. My pas doesn't work smoothly if magnet count is wrong with KT controller. I had a 12 pole disc and controller was set to read 10 and didn't deliver power properly, changed controller to read 12 poles and all worked perfectly. I can only assume that ...

Re: Front Hub Motor Not Working

A good job well done and a pleasing result Col :)

Unusual for motor cable not to have enough extra slack to form a drip loop in its entirety, periodically you could use a thick grease (non petroleum based) as a measure to help seal the axle.

Re: New e bike conversion PAS knowledge needed

11ah usually suggests the cells will most likely be Samsung but which cells ?
Are they mediocre 22F 4.4a rated or 22P 10a rated, there is a big difference in performance.
Cell sleeve colour is a pointer as is the marking on th sleeve.

Re: New e bike conversion PAS knowledge needed

Controller rating varies each pas level will have a different power/amp %. All are approximate. Pas 1 13% or less hence why you see 75w or so. Pas 2 20% Pas 3 33% PAS 4 50% PAS 5100% The reason you see 800w or near is the voltage x amp output. Although controller says 11a it will deliver double at 2...

Re: Front Hub Motor Not Working

Could be two or three reasons nothing major. The Clutch gears three nylon gears need to mesh in nicely with the hub body's fixed ring gear, so a bit of patience and manipulation by gently turning the axle shaft ACW & CW. Also on one end of the axle shaft there is a splined gear/cog this also nee...

Re: Front Hub Motor Not Working

Yes this I also mentioned in my post, the cable when it exits south (from under) then naturally will form a drip loop.
As in the pic water will track straight in to the hub easily filling it with water.

Re: Front Hub Motor Not Working

As I thought rust was stopping the motor from parting (didn't expect the inside to look that bad), the clean up looks a lot better. A good liberal coating of grease and only needs applying to the nylon cogs and the drive gear in the hub body needs to be one that doesn't harm plastic/nylon a non petr...

Re: Lady pedestrian fighting for life following ebike hit and run

It appears now that the lights were green and with the road traffic, the lady/pedestrian it seems ran the risk of running across the traffic flow in stead of waiting. So why the ebiker did a runner only he will know, maybe he just panicked in the aftermath of the incident and was not thinking straig...

Re: Lady pedestrian fighting for life following ebike hit and run
