Sensible Monday head on...I don't think friction drive will be good for transmitting the extra power needed for a cargo trike, especially on the (admittedly rare) occasions where it will be used in the wet. I was also slightly excited about regenerative braking but it seems marginal at best...

Thanks for all the support so far! As it's the weekend, I've been dreaming and casting my net a little further afield. I've been reading about a friction drive system that uses a brushless motor as the roller itself. Super low parts count! I'm not scared of a little bit of laser cutting and...

I'm (slowly!) coming around to the idea that buying a specific ebike battery is the safest thing to do given the demonstrably false advertising of the suppliers on AliExpress. Would something like this be a good choice...

Wow. I'm used to AliExpress vendors inflating their specs but that's in a different league!

Now, what about the battery? Is there any reason why I can't use a generic li-ion battery pack like this? https://a.aliexpress.com/_BSmIbu

I'd probably need to buy one before welding anything up

Good points all... I'm hoping that by using all new brake components I can go some way towards stopping efficiently. An upgrade to discs will be hard, won't it? Something to go away and research. Trying to keep wheels small and weight low down to minimise the centre of gravity as far as I can...

Looks like I might have picked the wrong time to do this project. Lots of people out of stock, prices going up all over the place. Boo to lockdown!

Yose Power sold out of antything suitable. Woosh have no kits until July. What about this one? https://www.ebay.co.uk/itm/223584081569

Thanks for the replies so far! I haven't actually welded the BB yet, so it could be done (I hope) in such a way as to allow a mid drive. Yes, there will be some more diagonals added around the BB as well as some bracing to the bottom of the pivot on the cargo platform.

Hi all, I'm in the process of building a Christiana-style trike for a friend of mine. She has an autistic son who can't ride a bike and neither she nor her husband drive, so the idea is to give them a bit more mobility. I'm thinking about adding some electric assist to the setup and would be...
