Re: Razor kart upgrader

Seems like an "escalation of force" problem. I mean sure you can upgrade the motor, but then you should probably upgrade the axles and then you probably don't want that much stress on the wheels/tires so upgrade that too, then the brakes won't stop you fast enough, then the ball joints ect ect...

Re: preferred method for stacking batteries end to end

18650 cells dont put out much current nd are fairly heavy.... so dont expect too much performance from them Right. For typical 5 minute "sporty" flights I like a good 30-40c, for 30 minute flights I want about 10c and for 1+ hours flights I only need 5c. For my intended use 3c is plenty fine. It wi...

Re: preferred method for stacking batteries end to end

How big is the pack ? That's sounds good for a flashlight. Like 3s for 12v . Not a bouncing ebike. Sorry I was thinking 3s 10ah. I'm into both electric bicycles and model airplanes. It would be for a long-skinny fuselage. For model airplane weight reduction reasons I probably won't be doing a full-...

The weight is comparable because a certain amount of magnet and copper is needed to accomplish the same task. 1. Cost: They are ...

Re: Solar Trailer Technical Advise

Well, you'll never get the full 100 watts. You can probably count on 70-80 watts under ideal conditions from a 100 watt panel.
Depends on the panel. I was pleasantly surprised to see my HQST 50w "flex panels" giving just a little more than 50 watts (measured at the wires)

I guess that sort of depends on how many whs you want to consume per day. I personally find myself creeping into the 2k per day mark at times. You won't get a full 100 watts out of that trailer during the morning and evening which is probably the time you want to charge. I would expect maybe 40-50w ...

Re: High powered Ebikes high speed suspension setup

The bike will "porpoise" if your shocks are too soft. You don't want to be leaning way forward after your wheel drops down deep in a dip. The bike will slam and try drive a bike up your innards/through your forearms if the shocks are too hard. Generally you want the shocks soft for casual use and wh...

Re: Advice for a newbie

Due to their more robust frame downhill and freeride bikes make the best bikes for what you are talking about. You can probably find a used one on Craigslist. You could put a large hub motor on the rear wheel but having single-tracked on both hub and mid-drive I find mid-drive to be better. Having m...

Re: How to identify antennas?

Presumably you just try them out and see what works best and this is because of impedance. Even among the same manufacturer antenna length varies and that's because loads are different from device to device. The materials used cause resistance and the antenna/device has to match. For instance when y...

It will be a 2000w+ middrive road bike I predict that it will work okay for the first several rides and then the teeth on both the chainring and the cassette side of the will start to wear a little. You will start to notice the chain "snagging" and the teeth will get to the point in which they are ...

Re: Need brakes upgrade for etrike conversion.

Aww too late, I was going to chime in and suggest one of those speed controllers that does PWM based regen. You pull a brake lever and your motor regenerates based on how hard you pull the "e-lever". Pulling the lever all the way down is enough to lock the rear wheel up. Glad you got the new front b...

Motors hit a point in which their efficiency drops due to overvolting. Your wh/mi numbers go up if you overvolt too much.

You would need to know the watt hours of your battery: ah x volts = wh for instance 10 amp hours x 44 volts = 440 watt hours 10 watt hours per mile = you are in good cycling condition and have an efficient bike 20wh/mi = pretty typical cyclist condition, pretty typical bike 30wh/mi = not atypical es...

1) you can flow as much voltage and amperage down that motor as you want; unless we are talking something super extreme the flow of electricity isn't what is going to kill it, it's overheating that will kill it. 2) Motors often have overvolt protection built into them so you can overvolt a little.
