My thoughts exactly... off to read the latest frame threads...

Apparently a Trek fuel is good for 7300 miles of e-biking. At lease mine was. Last week I started hearing a strange creaking sound. It got rapidly worse until something was very obviously wrong. It was really hard to see on a visual inspection but with someone sitting on the bike I found a break...

Thanks for all the advice. After a bit of time playing with the simulator it seems to agree with everyone. Short bursts of 2500 watts are not bad unless the speed of the motor is really low such as climbing dirt hills. In my particular use I cruise at 150-300 watts, unless it's a really windy...

I am curious how many people out there are running a 9C at or above 2500 watts. Also what sort of precautions have you taken, such as temp sensors, and what sort of problems have you faced?

More Power Muahahaha, Ok so the new setup has about 800 miles on the clock (plus the original 3k at 48v 20 amps) and I have decided to up the power. I have been running at 30-35 amps. Now I am bumping it up to 40. I think this will probably be the limit for me at least for a while. The main...

I purchased the 12 fet extreem modder controller from Lyen along with the three speed switch and cruise control. All plugged in and worked flawlessly. The only chages I made were to adapt the throttle , phase and hall connectors to be the same as my ebikes controller, for easy interchange.

Wait, a baby seat

Wheelie bars :P

a back seat :shock:

Thanks for the input. Methods "wife kits" with a 2810 might be the right fit for him. I've also been looking at the area on mapmyride.com. There are some routes he could take that would add a mile to the commute but the hills are on the 9%range. The next step is a battery. I'm tempted to...

A friend of mine is considering building an ebike to commute on. His main concern is a 12-13% grade that he will have to climb. It’s about .4 miles long then it flattens considerably. Personally it seems like a 9c 2808 or similar motor from ebikes would do the trick. I think he wants the bike to...

I like the idea of integrating the lvc cut so that it goes through the board. In my application I remove the battery pack twice a day. Each time dissconnecting the lvc plug. This doesn't bother me much except that I don't really know it works unless I test it each time. What I mean is if I...

I run Michilin City (puncture resistant) 2.3" x 26" 40psi front 60 psi rear. I'm about 170. It's not harsh but like Ykick I ride a full suspension bike

I have essentially the same bike http://endless-sphere.com/forums/viewtopic.php?f=3&t=34773 and 3400+ miles with about 20 lbs on the seat post. Treks are tough bikes unless there was some manufacturing defect I'm pretty sure the post would fail several times over before the frame did. Anyway I...

You can use the simulator on ebikes.ca to get an idea of your range with no pedaling. Even light pedaling will greatly extend your range. Since you don't want to fully discharge the pack and there is some question about how many amp hours are in those 8ah pack. You should plan conservativly...
