Re: electric bike with sidecar all in one

I have an aluminum box that fits between the wheel wells, with a little foam padding that can be used as a seat. It keeps a person's weight in the center line of the side car and it allows the passenger to hold the railing of each wheel well. For a child I would want to install a couple seats with h...

Re: electric bike with sidecar all in one

The ability to carry long loads, the greater simplicity of having a rear wheel motor with no differential set up or chain offset and having the drive wheels in line for greater traction control is the reason I built a side car rather than a trike. The battery is now S13 P23, I started with a 36V (s1...

electric bike with sidecar all in one

Necessity is the mother of invention, trite but no less true. I live on a small island in the straight of Georgia on the West Coast of Canada.. The road surface is very poor, there is no two meters of the pavements that are alike, The narrow roads are very twisty, up and down with average grades of ...

80A BMS for 75 A battery

I am building a 36V 10S 75Ah battery, I have not succeeded in sourcing a 36V 10s 75 A BMS, can I safely use a 36V 10S 80A BMS with an 80A over current protection

Re: 2wd one battery per motor or 1 battery for both?

Thank you for all the input, I am digesting it all and will come back with questions. It seems immediately obvious from both your experience and the time that you have taken with the simulator that I have to consider a higher voltage and more powerful motors. I live on Cortes Island where the hills ...

Re: 2wd one battery per motor or 1 battery for both?

Thank you I am just converting to electric propulsion so I have no experience I am reading as fast as I can. I was under the assumption that the 300 Samsung would give me a 36V 75Ah S10P30 battery, are you saying that no matter what I am limited to the 20Ah discharge rate of each cell. In your exper...

2wd one battery per motor or 1 battery for both?

I live in a remote hilly rural area, I am building a bike with a long side car, for passenger or cargo, like a few rounds of firewood. I will have a 36V500W geared motor on the front and rear of the bike. I have ordered 300 Samsung 25R5 20A 2500mAh to build a 36V system with Vruzend V2. I am going b...
