29er TREADMILL Motor EBIKE BUILD 60V

[DATABASE00]

HAHA, I know I started thinking that just recently after looking at everone elses pictures. But I just hear of alot of people not geting the speed they want so they over volt their units and fry them. and thiose are some expensive motors.

I agree about trying to make it look decent so your not ashamed to be out in public with it, always nice to be stopped and let people be amazed on what you have built.
the 10 inches is end to end including pulley tip.

how long is your motor you have on your back wheel?
with that small of chain is it pretty quiet?
do you ever runinto motor being unbalanced from motor hanging on one side?

Motor Dimensions: 4-1/4'' W x 6'' L not including shaft. 4-1/4'' W x 7'' L including shaft.

motor is pretty balanced no shaking or whatever i have spacers in b/w motor and motor mount and with two bolts holding the motor so i can adjust tightens of the chain, and chain is pretty wide compared to bicycle chain it is #415 chain and there is a nice not so loud sound kind of comforting.

overall setup of all crap on this bicycle is great i just need to decide on the motor i am just confused what is more important for the hills V or RPMS

i was also thinking of have 60volts for my controller and run 1 more 12volt batterry for accessories and a turbo button that will combine the output of 60 volts with additional 12 volts from spare batterry to give a turbo lol. ill wait to see how everythign acts at 60 before trying to make a turbo. I havnt seen what motors can do yet. maybe this weeeknd ill put it in tire to rest and see if it will run just by ting it down and a few batteries lol

just make sure to use correct wire gauge otherwise you will burn wires and create more problems

[darkangel]

later i will show you how to make battery connectors for parallel charging and serial motor run

i just got to find the dang link

[DATABASE00]

Have you heard of Battery Desulfator?
something to do woth golfcarts keeping the batteries working harder and longer?

[darkangel]

don't know much about it although,
I think its mainly used to protect battery from overvaluation and undervaluation so you don't end up with dead battery cells. it is good idea but its unnecessary if you have good controller

My bike build is very similar to what you have mind, I use a lawnmower motor which is 9 inch's end to end. Its a 2 stage reduction, the primary drive is out board and the secondary is in broad. I did it this way to keep the motor on center with the bike. The bike has several season on it and runs very good, no major issue's to date.

If interested I post picture's later

Good luck with build

I am very interested in pictures of similar projects.
I also came across these 50pack of 18650 batteries 150 bucks they are 5000mah and was thinking I could user 24 to make my 90volt batter to push my motor to full power if I needed. Make two so I can run in pair and make it last longer. It would definetly keep the bike weight down but not sure how far it would drive for. deffinetly allow for faster starts.
Ive also seen 90 degree angle gear reductions that I might land up using to put motor lower on frame..

so many choices so little time before I want to buy something else for this project LOL.

also found this controller 100volt 80 amp.
able to boost my 90volt motor just a little over voltage for those times I might need to push it.
