Hello - I have been ride leading out of Warminster park the past two years on Tuesday evenings.
I just put together an e-bike kit and I'd like to take it out and demo it and answer any questions you may have.
The bike I will be riding is described here endless-sphere.com/forums/viewtopic.php?f=6&t=235&start=1900


We will be leaving from the Warminster park pavilion at 5 pm. Probably around 20 miles. I will "lead from behind".

Feel free to contact me at:

Ride went well. This is the first, somewhat long, ride with the e-bike and I was really pleased how it performed.
Power assist was actually used sparingly. I think we did about 19 miles. The design goal of this bike was to have acceptable performance without power assist and that is what I explored on this ride. I probably used less the 5% of the battery's capacity.

I had one minor issue - the derailleur needs adjustment, it was hunting between 5th and 6th gear. All other gears were OK.
I don't know what it is, but the 46T chainring with the 11T on the top gear really works out well for me on the flats. No problem hitting 20mph+ on Hatboro Rd without power assist. No problems climbing the 6-8% grade on Wilkinson without power assist.

I gave a short boost on Wilkinson and it's was pretty clear that without pedaling I probably could have done 10-15mpn and probably 20 if I boosted and pedaled in combination.

A few interesting observations:
Electric boost is real handy at traffic busy intersections and stop lights. It actually makes the bike safer. You can give a quick blast of the throttle to quickly start off and get through critical situations.

Electric boost can help minimize irritating gear changes. For example you hit a small roller and instead of downshifting you can give a quick blast and stay in your top gear. It often does not take much, like a 5-10 second blast.

Given how little I used the electric boost on this ride I can foresee the 14amp hour battery easily lasting a 70-80 mile ride down to the shore, where you just used it for the tough spots or towards the end of the ride when you are tired. Definitely provides the means to go further than normal. I think i will build a second, lighter, and lower capacity battery for use on shorter rides.

I plan to ride the bike over to Hollicong park for the picnic ride on the 26th and can do a question and answer session after lunch.
