I am thinking about buying the ebike/scooter in the attached picture. It presently has a 48v (probably 500 watt motor) and a 20ah SLA battery. I am hoping the final "product" will be 72v or 96v w/ 1500 watts and a 50ah LiFe battery with a significantly more sophisticated controller (regen, cruise control, reverse, etc)...quite a change, but I am hoping to do it in stages.
My first question: the headlight assemblies on this bike are heavily oxidized. Is it possible to buy replacements? The dealers here (I live in Beijing) all say it is impossible but I know that they are trying to get me to buy a new bike. I don't want a new one because, IMHO, they are not any safer than the used one I am looking at, and I think many of the mods I want to make will make the scooter safer. Most people ride these 4-6 miles at a time. I plan on doing 12-15, one way, and then the return, so I want things to be more durable and safer than the new ones will provide. If replacements are not possible, I have seen cleaning liquids advertised that will removed oxidation from car headlamps. Will they also work for this?
2. 48v @ 500w to 72v or 96v @ 1,500w is a big power change, especially in the torque. I was thinking about contacting a custom fabrication shop and building a new rear fork for it - cost to me probably $200 Are there other options?
3. The bike comes with drum brakes front and rear, that are attached to the left side of the wheel. The new motors I am looking at have assemblies for disk brakes. Can I attach an assembly to the rear fork to make the change to disk?
Thanks in advance!
