Re: How many of you really use the wiki?

I have been here for about a decade, 6years under this username.
To answer your question accurately I apologize but my answer is also a question.

Re: Using bicycle's frame as heatsink for the Phaserunner

I just want to point out that even if you put it in a bucket of room temp water, and kept the water at that temp, you EVENTUALLY will burn up the phase runner if you keep pulling maximum phase current from it. The thermal path from the mosfet die to the mosfet package can only support so much heat t...

As long as you dont need current limiting or a voltage cutoff, it works well.

Re: more powerful brushed controller

The Kelly is much higher quality than the Yi-Yun units. The lack of current limiting on the YK43 is probably why it blew up. It works OK if your pack voltage is low enough or the motor resistance is high enough so that limits the current to something in the survival range. yeah, I ran one of those ...

Re: Why are more of you DIYers not in the e-bike business?

I think others have put it into good terms on why not to get into the ebike business. Here is my reason why I got out. People want you to make all the decisions, do all the leg work, tell them what to do to build a bike. Then they buy $30 in spokes after taking a few hours in time. Hey, you do real...

Re: Hearing protection while riding

With the winter lining, I have no wind noise, and my hearing of the environment is almost the same. In the summer, I don’t feel the need, and I don’t wear a helmet most of the time.

Re: R Martin EVD Moped with HubMonster

I've been hunting for another of these motors or moped. I did find a motor a couple of weeks ago, but it had already been sold. If I want to drive 1800 miles, I found another R Martin. I was hoping for something a bit closer. Maybe I can get the seller to crate up the bike and ship it to me. If you...

Re: Wheelies

Re: R Martin EVD Moped with HubMonster

Random thought... if you took one of those hub motors that bolted to the rim, and instead bolted a chainring on it... would it be a good choice for a gokart motor? I mean you could gear it up or down a bit to match the wheel size... although 1:1 is probably about right since you want good accelerati...

Re: Wheelies

I learned on 50cc pitbike motards... started with them, then dirtbikes, then sportbikes.
wheelies on ebikes that have amp or torque based throttles is easy.
wheelies on ebikes that use speed throttles or laggy throttles is a bit harder.

Re: Anyway of making the R martins from china sold on Ali express road legal in U.S.

The act of importing them for road use is federal.
The act of registering, titling and how you may drive them on the road is state.

Re: Anyway of making the R martins from china sold on Ali express road legal in U.S.

Ignoring the fact there are countries other than the USA.... Just in the USA there are 50 states, and all of them individually have their own different laws for classifying and registering vehicles.
so no matter what you say... theres probably a state where you're wrong. :lol:

That ESR750, Was that a lithium ion battery and brushless motor? All of them run the same brushed DC motor. You can get them in lead acid or lithium, but the difference is weight and range, not top speed or acceleration. If you get an upgraded motor, you can accelerate faster or gear it to go faste...

Re: Challenge with brakes

My guess is that those mounts are for some kind of lock, not a brake. I once had a similar puzzle in trying to fit a rear brake on a de-electrified junky e-bike that had previously used a band brake. I ended up mounting a long reach caliper brake under the kickstand plate. In my case, losing the ki...
