Is there anyone else or another company you would recommend looking into?mr.electric said:I like thier product offerings, BMC, nice batteries, KHS bikes. They seem a bit sloppy on the full ebike build quality - Trying to save money on zip ties?
I don't think you will get 40mph and reliable in one bike. Unless you spend a fair number of hours tinkering like all the forum members you will be dissapointed in a fast ebike. It seems like Dogman is one of the few riders who spends a greater number of hours riding than tinkering.Over 5k miles wow. I think I have at least 2 times the tinker hours to riding hours.GTR2EBIKE said:I'm looking for a fast reliable e-bike and there "40 mph" bike sounds like a good amount of speed to me. Anyone you know of that builds one with a similar or higher speed?
cell_man said:The choices to get 40mph are either a big direct drive as has been suggested or you could try a pair of geared hub motors. I've been using a pair of high speed Mac/Puma motors in my bike and at 48V it hits about 64kph on the flat or about 40mph. I have my doubts that a single BMC motor will actually do a genuine 40mph and I can't see it doing it for long. You need quite a bit of power to do that sort of speed, close to 3KW, so you'll need a good battery too. I run just over 30A current limit on each controller so around 65A total under acceleration with peaks above that. The standard rpm motors will not do that speed at that voltage, you'd need to run them at a higher voltage but you might find they run more efficiently with higher volts, lower amps.

On the other hand, I got a rare 1000w BMC Direct Drive proto-type they got last year (1 out of 3 I believe) and this thing does 40mph at 48v (A123). I don't know what happened to their DD offering but its been solid and better than 600w geared one I have.
To get a 40 miler with most motors, you have to forgo some of the creature comfort - like front and rear suspension, thick tire, granny gears, etc.
dogman said:I agree about the speed, 30 mph is about tops for riding on public streets on regular bike frames.
That is, typical bikes under $500. DH frames are another animal, and I can really feel how they are made for those speeds, and the suspension can eat up the bumps easily. I'm working on a bike now to go at least 40 mph, but that is for the death race and will be run on a racetrack where missing a corner is survivable.
A 9 continent 9x7-2807 gets up to pretty decent speed for street use at 48v, reaching 27 mph. The 2806 oughta see 30 mph easily. Plenty for riding on a bike trail, or residential back streets with 25 mph speedlimits.
If 30 mph is the goal, then it doesn't take a very exotic motor. 2806, aotema, clyte 406, etc does it.
Electress said:Just a little input from a non-biased party. This is not to be mistaken as a bashing.You shouldn`t have to be a lawyer to purchase ANYTHING online or via telephone. When you put your money up for a purchase you should get exactly what you ordered in a TIMELY manner. When you run a "business" the customer should be respected as they respected you at the time of purchase. So if these things were applied, there wouldnt be all this B.S. If there was a problem shipping out the order your company, Hi Power Cycles should have as a "business" contacted your customer and communicated with him or her what the problem was instead of ignoring the phone calls, since you already had his / her money in your bank account. We as the consumer trust in our business owners way too often and in my opinion the reason we do is because we want to trust you and build a business relationship with you for future needs. I guess what gets me the most about this is that Im sure you dont know the personal circumstances of each and everyone of your customers but you dont know how your actions could have or did impact your customer. Maybe this motor was his ONLY means of daily transportation? Or maybe you dont care? Im thinking you dont care about your customers due to taking your sweet time in mailing what was already paid for, not returning calls during your normal business hours then saying a "loaner" motor was in the mail. (but never recieved) Im taking bets you will be out of "business" soon if you dont take these comments and generate them into "Better Customer Service"
