Hi there Aussie Jester, thanks for your photochop, I like your change. It's uncanny, I have currently got the sissybar off and I am converting it to a suspension set up and was I considering lowering it. I will post photos. The motor is 135mm dia and 200mm total length including the shaft. The batte...

You don't need that many gear steps with a motor. I tend to agree. It all depends on your power to weight ratio. If you use a "monster motor" then you need less in the form of gears. :D I hear you. 1000w/3 gears works well for me. I just love over powered machines. Here in Western Australia the leg...

I suspect that a wide ratio three speed would be the way to go with a chain drive. You don't need that many gear steps with a motor. But nothing beats a test for information. I tend to agree. I find that I start off in 1st, hold it briefly, then go straight to 3rd. 2nd can be handy up hills when 3r...

[quote="Ben"]Say, what current does the motor draw at top speed?

It spikes at over 50Amps if you give it a full handful while accelerating, but it is around 40 amps at top speed on the flat.
Cheers,
Matt.

Thanks link I have opened my eyes now. Not sure, but it looks like you have 2 of the batts upside down.. i'm pretty sure it's ok to mound SLA in any position but upside down.. ? might have something to do with the low output. Nice build ! and lithium will make that bike scream !!! I'm pretty sure th...

How do you quote someone in your post. ie the grey box that says "so and so wrote.
Cheers,
Matt.

I got 3Ah out of it today, but the during the last 1Ah it was cutting out, if I pulled too many amps, due to the controllers low voltage cut out. The controller is designed for Lipos so maybe the low voltage cutout is too high for SLAs?? What voltage on a 48V SLA system is considered a deep discharg...

Thanks for the replys. Lenk 42602, yes I did cut and weld the frame myself. Link, I bought the batts brand new and they all had 13.2V, but I have been very disapointed with them. When they were new, the best I ever got was 6Ah. I can only get about 2 Ah now after about 100 charges. I am only pulling...
