I see, I’ll will look into hub motors for sure now , has been mentions by Az also.
Start with food delivery. Put some effort into it and at the end of the day you might not need to go to the gym
48v gets you 30% more capacity and gives you more options for the amount of power. They're around £300 for a 20Ah one from Greenace. You're not going to do 5 hrs with one battery unless you do a lot of pedalling and I wouldn't use a crank-drive for that sort of riding.
Looking stay in level speed limits so 15.5mphmore speed = more power = more waight so if you want to do 50mph with no effort its not going to happen.
nothing that delvers food to me is road legal gangs of um outside mcdonalds ect even plod uses them
Yes 48v seems better and £300 is decent, ah ok so you suggest a hub drive also. I’ll be going over London Bridge quite a lot, will a hub drive be ok for that? Reason I started looking into mid drives in the first place was that it seemed better for riding up inclines compared to hub.
It's an urban myths that hub motors don't climb hills as well as crank drives. If you run with 48v, a hub-motor can tackle any normal hill with ease. You get 30% extra torque compared with 36v.
Crank motors should be confined to off-road use only. They don't make sense for a bike that's going to be used on the road.
Ah yh that’s looks much steeper then London Bridge! I’m 100kg so with my backpack or food delivery bag I would be 105-110kg. Would you guys deffo recommend 48v over 36v. And does front or rear hub make a big difference. I’m starting to like the idea of less maintenance.
48V rear hub seems like an optimal solution for you. 48V is maximum legal voltage. It will give you extra omph.
Also keep in mind legal limit is on motor rated power, not on power provided by controller, so you can have very powerful legal bike if you want to.
A 48v 17A controller will give you 816w on maximum. For this you would need a battery capable of delivering at least 20A. Note this 20amps not 20Ah, this is the capacity.
Here's an AKM100cst 250w as an example. Although rated at 36v, if you bought the 201rpm version and ran it at 48v it would give you the rpm you need.
Of course it depends on gear mounting, cassette or screw on.
Although , as a first time conversion, it might be wise to give Woosh a go. You'll get all the advice you need prior to buying.

The 816w is average nominal power from the battery and not the motor, typically one may acheive approx. 600w or so from the motor at max assist power. With a charged battery one likely may see 700w +/- 25w motor power for a while.
How the riding power is delivered is dependant on the controller system used .
