About 100 miles with the 20mph mod. I have been "pedal assisting", with my, bought last year, used-abused, batteries replaced , used-abused some more, original battery pack. Noticeably degraded from new pack, I made a few comparison runs.

So far I've had no trouble maintaining 20mph on a 10 mile, fairly level, blacktop trail. Usually I run it twice a day, morning and evening, when its cool.

I would recommend this modification as, the cheapest & most effective. It helps the EZip reach its "proper" potential. Motor speed now matches pedal assist capability, sustainable at 20mph, and with some assist and vigorous pedaling, above 22mph! Yes, it will run 20mph, motor only, reduced range, of course. And most importantly it still complies with federal definition of "Bicycle". Making it "street legal". Test with speedometer, right near 20mph. If testing-certification required, either, use partially charged battery, or, reduce tire pressure slightly, to guarantee not exceeding 20mph.

Only problem I foresee is that Li-ion batteries can't be constructed into a 24v pack. The closest I can come is 25.9v. (22.2v is not acceptable) Yes, I will give it a try. I will rearrange the cells in one of my 37v 20ah pack into a 25.9v 30ah pack, will require the 80 cells +4 additional. Still smaller, and much lighter than EZip OEM battery pack. The little more speed, provided by extra voltage, couldn't hurt ... me.

First I will test jumper from the 25.9v point, of my 37v pack, to confirm that it doesn't exceed the "over-voltage " protection, of my 24v controller.

Will keep everyone apprised of my progress.

Bike still runs just fine if you want to use partial throttle and idle along at 15-16mph.






PS. I'm working on a much better method of freewheel removal, already successfull with a new wheel. will post details after successfull removal of remaining 500 mile used freewheel.




Work! Work! Work!







WARNING! Don't watch this, too long. It's better than counting sheep.
