Yeah. Something sure isn't right. That's for sure. It's like they changed it so it would cut off at 20 mph no matter what. Unless of course you're in Turbo Mode which gets you about ten miles to a full charge... Interestingly, the settings in the software were set on "20 mph" but I was told by Cameron that those have been disabled... Huh. I guess we'll see what happens when Rakesh calls. I'll report back if anything good happens.I am sure they can make it work for you. The controller is key. You just need to get the update or hack the software.
You might want to exchange it. I would only consider the 1.5kW motor. It requires a wide dropout, about 175mm. I am not sure how many gears it would take, either. So I would need something like a pinion gearbox on the crank.
That motor can reach 30mph on my 10% grade. I would love to race cars up the hill the speed limit is 35. I think I could 40+ mph. I run up the hill about 10mph.
Side Note: I don't think the 1500 watt motor is available in the US. I think 750 watt is as big as you can go. Would upgrading the Battery to 48V help? Thing is... I'm about 85% sure I'm probably going to end up having to buy another e-bike if we can't fix this one. I wouldn't enjoy using this thing the way it is. If I do, this one will never get used and I don't want to put any more money into it... It's kind of a sucky situation.
Side Note II: Oh I see you are in Redwood City. I guess you can get the 1500 watt in the US. Where did you buy it?
