solar bakfiets
New Member
Hello all,
My name is Dirk and i'm planning on converting a bakfiets(cargo bike) to a electric assisted one.
I'm from the Netherlands near Enschede.
Pictures:
Because there is a lot of space and its cool i want to incorporate a 80W solar panel and multiple lead acid batteries in the design to achieve a long range.
The big question is what type of motor to use.
I'm thinking of using a 750 W Bafang BBS02 48V mid drive, because it seems like a relative simple to implement option. It also has a lot of torque which is nice when accelerating with a heavy bike.
What are your thoughts about this combination?
Is there an option to implement a walk assist until 6kmh(4 Mph) to compensate for the lack of feedback from the speed sensor at low speeds?
Can you program a maximum speed? (some sellers claim you can but its not clear for me)
Your thoughts will be appreciated.
For your information: i'm a mechanical engineering student with machining and welding experience so modifications won't be a problem. I also have some friends studying electrical engineering that can help me if i i'm having troubles with the electronics.
Greetings,
Dirk
