Isn't there a requirement for odometer disclosure if he ever sells the chassis?

That's one helluvan RC!
I think, firstly I will go to my local motor winder, if he even trades anymore.
But I really like the look of those RC motors, think I might HAVE to experiment with them, even if just to be able to say its powered from a remote control toy if anyone asks

Ah that's good, didn't really want to keep the old clocks, wasn't sure if mileage needed to be kept recorded for MOT purposes

For the odometer, if I recorded the mileage prior then used a digital one I will be keeping the record legit, be nice to have a clean meter to see how much I'm electric

Odometer disclosure is not required in Oregon if the vehicle is over ten years old.

well looks like I get to keep my original budget for the motor

just need to find it somewhere available to buy now

speedometer and odometer I think I will manage with a cycle computer, with a fabricated array of (lights, full beam, indicators) underneath. An ammeter will be mounted onto the tank

Hopefully I will be receiving my donor bike over the weekend, a true mystery all I know is it's a 125 and was £20, then I can get some proper planning going.

That Turnigy motor has a maximum power output of 7 kW, so its continuous rating is likely to be half of that or less. 7 kW could get you to 60 mph, but the motor will overheat quickly at that power level. Remember these motors are designed to be mounted in the airstream behind a prop, where they have very effective cooling. Just to warn you that you pay a price for the low weight of these motors, they are much more susceptible to overheating than a big series-wound motor, which has a lot of thermal mass.

The motor used in the project I linked to earlier is rated at 12 kW continuous. I would try to find something closer to that.

I found the link I was looking for: http://endless-sphere.com/forums/vie...728&start=1530

This is a motor still under development, and they're still working on a controller capable of running it for high-torque applications. The thread is over a hundred pages long...

Ah thanks Malcolm!

Looking at the Turnigy there have been several successful conversions of small bikes and mopeds, so I might not get my goal of burning off the mopeds, but I do get my dream of an electric commute.
Whereas the nice looking motor in your link may be something I upgrade to in the future

Cooling yes I agree, I will have to have a think, maybe look at farbicating a larger scale version of how the smaller outrunners self cool with the rotor on back, coupled with blasting air at it through scoops at the front

So now I know my motor, I get to plan my batteries
and in a couple of days hopefully I will have my bike

excited

I weigh 55kgs and my target range is 30miles. My commute has one hill that I see could be a problem, for 1/4 of a mile. Speed wise 60 would be nice, but will likely aim for 40mph. Lead acid batteries will be the batteries of choice, atleast to begin with.

I guess my question, (which is likely a very common and annoying one, so I apologise), is what sort of motor can I get away with for such a set up?

This is to be a budget bike, so I can save my fuel money to tackle a more financed build.
Ideally my motor budget would have been £100 (you can laugh don't worry)
I have been trawling ebay, but the only thing I have really found was only 620w Emoteq, which does not sound anywhere near the mark?

Aslong as I can (just) burn off a moped still I will be happy

Any suggestions / criticism would be appreciated

Many Thanks

Jimmy

Check out the Mars 709 it will work for that bike you are building.

Glad to help. I think if I was starting again I'd go for this 'Bantam' approach as well, keeping everything light and simple. It just seems to be the best fit with electric technology at the moment, for leisure/commuter use anyway. Keep us up to date with your progress!

[datahar]

ooo A bantham now that'd be a nice conversion
Attached is a graph of my commute one way, looking at it like that makes my task seem even more daunting, but that's my target


otp57, Thanks I had a brief look at work, but couldn't seem to find a seller of that motor unfortunately
