I agree with you, I have had the misfortune of riding the bike with dead battery, good quad workout.. However, the folding function is a quality that is hard to quantify. I've travelled with it on Trains and such and had a really good time using it to explore this summer.

Sounds to me like you do have a technical solution in mind? I'd be interested to hear it. Although I don't have the soldering skills or gear(although gear is easy to get), I'd be interested to know what you'd suggest if I in fact had the skills and gear. The amount really is flexible. I am...

I'll try to provide more information such as budget limitation in future posts. But the problem is I am exploring and learning about the subject myself, hence the vagueness.

Because why not? I need to buy a new controller anyway. The controllers at 15-25-30amp rating are at almost the same price point. I also have found a decent priced 60V Battery, my thinking was to be able use both 48V and 60V with the same form-factor of battery. But as explained in this...

The goal is to sell the bike eventually. So I prefer not to invest in stuff that is unlikely to be a selling point. Beside, I am limited to 130x100mm, I have not found a programmable controller that would fit, if you know one, feel free to share.

180cm, The saddle is in hip height as I have bought a longer seatpost + one of those Steel "Feathers" suspension giving me an additional few centimeter. I prefer a higher riding position

This is the bike in question.

Oh really.. Thats a major drawback, I thought Controllers were able to be used with lower voltage than rated.

I believe the motor is able to output 750W as claimed by the manufacturer, which seems to correspond well with real life performance. Full charge of battery and I can reach 40-41Kph without pedaling. So that is Moped performance, but obviously looking for more. I will weight the wheel when I...

Programmable Controller is an interesting option, but they seem be at least double or triple the price point. I could probably get another motor for the front with the same money invested. There is also space limitation, the ones I've come across would not fit in my the space of 130x100mm. If...

Indeed there is a space limitation. 130mm x 100mm is the available space. Original controller was 85mm in length. I found some 9mosfet controllers(25-30A) that is 120mm, I contemplated the idea of fitting two controllers in there. One 9Mosfet and one 6Mosfet and maybe have some kind of switch...

I asked the supplier, and the motor is 48V25A, Brand: Lvdong. I guess I could get a 25A 60V Controller? I realize it is likely to lead to an early death of battery. If there is no built in protection, what is the easiest way to have a kind of switch or similar? When activated it will limit...

The current situation with my E-Bike is that water got in to the controller space in the bottom of the frame. Controller is broken and need replacement. The E-Bike uses the Silverfish Battery formfactor, I am thinking I might want a 60V Battery with more current capacity in the future. Hence I...
