once again another update.

i got myself 2 brand new 20ah batteries and a 36v 500w controller today. i lowered the final gear to 21teeth once again to lower motor(more so the gearbox) strain. i got my friend to follow me in his car and i got to a grand total of 32mph. battery was still showing a full 5 bars on the readout after 15 minutes of playing around.

the motor also felt a lot colder than when i ran it on a 24v 500w controller of the same make/brand. which i thought was weird. (thougth/comments on this matter?)

then i let my friend have a go and he managed to once again strip the teeth of the plastic gearbox gear

so as i mentioned in another post i definately need a metal gear cut. which is next on my agenda.

i have finally reached that point in the project when im seeing the top of the hill and how im going to get there. 30mph+ with decent acceleration for what seemingly could be an hour or more is exactly what i wanted. it makes the bike feel usable and not a liability on the road.

comparing this to what you can buy instead of building i think ive done rather well, especially on the cash front.

bike - free (given to me at work)
motor - £10
batteries - £70 2 new at 30 a pop and one i got froma junk shop for a tenner
controller - £10
sprockets - £15 i got a set of 9 11 and 13t
twist throttle - £15
battery holders x 4 - £20 i got 4 used trolleys with holders/motors etc on ebay all for 20
cable - free ,any high amp flexible cable will do really)

so far £140 + plus whatever this new gear is to cut and im still well under anything else you can buy
