Finally!

Ok, So I've had the bike for about a month now and finally got my cyclometer hooked up to it. I went to the flattest street near my house and set about measuring my max speed. The first direction I managed to reach 23.6 mph, going back I managed 25.8 mph. Averaging the two values I get about 24.7 mph top speed on flats. Bear in mind that if I have a slight downhill I can reach speeds of 28-29 mph. Tire pressure was 60psi for this test and total weight of bike and rider is roughly 300 pounds.

I also found that my 3/4 throttle speed I use for max distance puts me at about 16 mph, right where cyclone says I should be.

I also bought a turnigy watt meter and power analyzer that I need to install to see how much juice I'm using on that massive hill I have to conquer. More on that after the install.

So for all you folks that were looking for actual speed numbers, I'd say expect an average of 26-27 mph if you go full throttle. Once the motor reaches the efficiency mark of 26 on a downhill it's pretty much able to sustain it on the flats.


P.S. The street I used was a little over a quarter mile long.

More Pics

My finished ebike, you can see my beastly Kryptonite chain and lock
















The insanely long power cord(I'm going to have to shorten it but it came in handy as a backpack cord)
















Things left to do:
1) Mount fenders on bike
2) Mount cyclocomputer
3) Trim shifter cable
4) Mount bike rack
5) ??build aluminum hard case for battery??

I Think I Can, I Think I Can.....

For the bikes maiden voyage I decided to go up the first rise of the hill on my way to school. I was cruising along and the bike was doing great. I crested the hill in fourth gear and kept on going. I was so please with the result and performance of the bike that I decided to climb the entire first rise of my school journey. This mountain I have to climb is a 6% grade a mile and a quarter in length. I usually have to walk it, but with the motor I climbed it like I had an Olympic runner pushing me the whole way. I alternated between third and fourth gear and yes I had to peddle, but it was less effort than riding on a flat road without the motor.  

This was the first time I had ridden down this particular hill and I must say it was A RUSH! I don't have my speedometer on my bike yet but I think I was doing a downhill speed of between 35 and 40 miles per hour. The cars that were passing me weren't going much faster than I was and I was almost to the point that I could take a lane. 

It took me around 20 minutes for the round trip, I didn't time it this time, and I figure it only took me 5 minutes to get home from the top of the hill.
