Thinking of going the 48v route will 12.5 ah be big enough for modest journeys? With 750wbafan

[it is i footpump]

Hi all for some time know myself and a mate have considered going for a bafang 750w center moter and 48v battery.

yesterday met someone i know who has had various ebike set ups, currently running bafang 750 w in conjuntion with yosepower 48v. 20ah battery which is rear rack mounted. But is heavy at 6.5kg, Rider is light at 11 stone and has two sets of wheels for his ebike
Mountain style wheels and a thinner set for flatter terrain. Range about 100 miles level terrain. Power setting 2-3

i am thinking of a simular set up ,but yosepower do not do a large 48v downtube battery only a 12.5ah. Which i think is 4.5 kg

i am 14 stone ,mainly flat terrain but i do use high levels of assistance on the 3 ebikes i own ,dure to not being able to put much weight on right leg.

the bafang is 120 nm. My tdz2 is 60nm ,my bosch 50nm.

i have no idea what sort of range a 75ow bafang At say level 2 assistance with a 12.4 ah battery Would give.
I have to take my ebikes up and down steps and the rear rack battery may be a bit heavy,

costs are goodn12.5ah 48v £208. 20ah. 48v with rear rack. £341. Uk sourced

Yours views please

For the 750w Bafang, you need a battery capable of delivering 20A continuously. Without looking up the spec, I'm pretty sure that the Yose one is 15A. You should check.
