Where's the speed?
Hi all! I recently rebuilt a 1984 Melex that has been stretched limo style and lifted 4" and on 22" ATV tires. I am running 8 6v Deka Gc15's brand new, an Alltrax Axe 4865 500 amp controller, and an Advanced fleet speed ch-4001 48v motor. Everything is wired together with 2/0 welding cable. I have programmed the controller to 100% current, 100% speed, ensured that all tires were inflated to 20 psi, but it tops out at 14 mph. 1/2 speed reverse is not enabled and i tried reversing s1 and s2 just in case. The torque in this cart is unbelievable, it will downright throw you off the back of the cart without the seat backs if you stab the accelerator, but it is so lackluster at speed. I was expecting at least 18- what gives?

Re: Where's the speed?
It sounds like you either have a very low geared rear end or the motor is low rpms?

I reached out to plum quick via their website yesterday with several questions about turnaround time, whether 25% was an average increase in speed to expect from a bandit conversion, how to ship, will I retain my stock shaft, etc. I explained my situation in the form, and I got back one response "if you have great torque, put 8:1 gears in your cart". No answers to any of my questions about their bandit conversion. Gear changes are more involved, more time consuming, and more expensive than a motor swap, otherwise I would be going that direction. Little off putting that I can't get answers to my questions about their product. I replied yesterday and again asked for answers, but have not heard back.

Sorry, got a response back last night, stuck in spam folder. Said I really should look into high speed gears and that they are priced about the same as the conversion. Why are they trying to convince me not to buy their product? It costs less, is easier to do, and I know it will work. I don't even know if the high speed gears from an 88 and up ezgo (the closest i can find) will fit an 84 Melex rear end.

I'm already running 22" tires and have to trim my wheel openings a bit more to prevent any rubbing during turns or with heavy weight, so taller tires are out of the question. Sent from my iPad using Tapatalk HD |
