Re: Special 6-seater bike build

Another prospective location is underneath the rear two seats, with the motor chains and large chainrings running through openings cut in the floor plate (or that section of the floor removed entirely). In that case, it probably would be a good idea to install a kick plate between the front edge of...

Re: Special 6-seater bike build

The brakes on that machine are friction and could use an upgrade, any plans for adding some bike disc brakes to it? You are right about the breaks, just friction based. I thought about some upgrade, but for now they were working alright. Enough breaking power to block the wheels. Maybe with the ele...

Re: Special 6-seater bike build

No cup holders on that thing :( No worries, as a German i made sure to have some. It's the grey tubes in front of every seat :) Its easier and cheaper to limit power then it is to make more, higher power. I was going to say Leaf 1500w hub motor if you want two motors, or a single qs 3000w hub motor...

The sprocket for the pedals would still have the freehub. If i can also use a freehub for each motor would be up for testing, but as mentioned i don't ...

Re: Special 6-seater bike build

Thanks for linking the two graphs. I think the suggested motor will not be suitable for the targeted low speeds of around 7km/h (4,5mph), as there seems to be a bad efficiency for any (hub)motor without proper gearing. I now measured the wheel diameter which is 14". Now the main problem then is...

Re: Special 6-seater bike build

Ah sorry, this is the english link: Aliexpress Sadly the motor doesn't have a clutch so i'm not exactly sure how it will behave when coasting. The feature of peddling isn't that important to me, it wouldn't be a problem to remove the chain of the motor just in case the battery will run out one day. ...
