How did you get on - I was thinking of buying an old 300 PAck and recelling it - are there any links to resources showing how to do it? also if I have to stick to 18650 cells can I use 3000mAh 20A to end up witha 20A battery?

OK this is a fun project for me and I dont expect to get over 10mph, and I wouldnt want to on this rig anyway. I dont care much about weight - its never going to light weight anyway. what I need is low end power so the same as chugging along in low ratios on a land rover. Just done some quick...

Thas fine what would you recommend? Overall budget £300

I am planning on a Cog on the motor 21 teeth smaller than a Granny ring - ordered from velosolo, then on the cog on the drive shaft i will do the same size 21 teeth, so it compares to pedalling on the granny ring and half way up the cassette normally and if you pedal very fast you are maxing out...

Cheers - the cassette is a 7 speed cheapo Shimano i just took it apart to see if I could jam it up, but It was too cold to fiddle around in my garage! I am planning on welding a sprocet on the left hand side black collar thing, after I get the powered hub in with the sprocet on the disc mount...

OK to today I have made sure I can fit a 135mm hub in the rear stays, it was actually on 130mm (god knows why?) but I have packed it out at the rear and its is 137 now! should should take the Bafang 138, and it shouldnt work loose when riding it! Tolerances are very tight but looks like it...

checked rear diff area:( I have 110mm clearance but looking a my drive shafts I am not sure the diff would go in easily? so I might connect the hub motor to the left hand drive shaft - to make sure it works and then fit a diff later on. So I will need a large cog here and a small one on the...

Cheers anotherkiwi that sounds champion so now my shopping list looks like rear dif (assume this can mount either way around) Hub only motor 135 axle (needs to be less than 20cm diameter) disc bolt cog on the hub to provide drive to the dif given my hub motor diameter restriction - which volt...

Just checked and there is about 10cm clearance from the second set of drop outs and the rear frame. So I could use the hub only option so long as the hub was less than 20cm diameter?

Cheers Wheels are 24" I have measure the rear drop outs of the frame ( where the rear axle is bolted on) and it is 135mm. so I reckon the simplest option would be to remove the rear end and pop in a 24 driven rear wheel - but it doesnt have rack mounts so I would need some sort of bolt on...

thanks D8 I was thinking about a chain drive motor - like those used on rickshaws- but the hub idea might work also I will measure those forward facing slots - any idea what they are intended for. Anyway can you you guys point in the direction of a retailer that can supply a chain drive motor...

I want to electrify this it is a heavy bike and I am 14 stone - it also pulls a large Tomcat Trailer bike for my daughter I dont wat to go fast just, say 7mph, for a couple of hours. It pedals ok but its not easy riding its has the usual trike bolt on rear end What are my options?

Well its not actually a trike but a quad - but it has a normal Trike style rear end I am using to pull a trailer bike and I want to motorize it for slow running/ heaving load. wheels are 24" I thought I could just get 2 electric wheels on the back but with this hub Type I am not sure What...
