Re: E-14 Rohloff "The Ultimate Electric Bike Transmission"

Roholf is very expansive to buy and PITA to repair. I find better building enough power to ride simple DD, for gears are making so many extra parts that can (and will) fail.

Re: 2 Controlles one motor

Note that controller heating is motor current dominated, reducing battery current by increasing battery voltage does not reduce controller heating significantly because motor current is not affected by this, the only thing that reduces motor current is reducing torque or changing windings. Current ...

Re: 2 Controlles one motor

Depending of the mosfets in the controller and the winding of the motor, to upgrad and feed higher Amps might run cooler. That is because Amps limiting is a major factor of controller heat. Same number and type of mosfets; more amps, less heat. Cool! (I wonder why they bother producing 9/12/18 mosf...

Since they have no visible brand, it is difficult to search for them. Yet I believe I saw one on Alibaba a few years ago. Here is a clear view:

Re: ES Crowd-Funding (Ebike Rentals/Sharing)

Some are riding them basic until the SLA are finished, those who can afford are buying them with all the options. The idea is that the entry market is cheap, but has a good base that can be upgraded when clients are ready to spend more. Because they are all the same base, they are serviced quick and...

Re: Aluminum vs Steel vs Carbon E-bike Frames

A few more years, and we can find used DH racing CF frames for a good price. Some are made very thick, and soon to be replaced for lighter, since the DH racing courses are getting better and more technical, and often won on crank work.

Re: shared mobility principles for livable cities

I agree with all but slower. Smaller and lighter is faster, in a city designed for big vehicles. Even at similar speed, travels will be faster without the heavy trafic. Then, because the flow will be better, faster speed limitations will be possible. The problem with speed in the city is it takes u...

The history of mankind is full of people who believed that they were safe. Safety is an illusion at best, a dangerous state of mind at worse.

Our cities need to be clean and efficient. That would be better for the people than any safety laws.

Re: H3540 bearing replacement

When you put a new bearing, press it in the cover bearing seat, using SKF bearing paste if necessary. Never hit or hammer it down, for this will damage the bearing and compromise its reliability.
