Since the MAC has 16 poles as opposed to 8 of the competitor motors and 12 turn windings i expect a good torque from it. Their battery cells are also capable of delivering high currents.
Sure its going to cost me some bucks. But i will have a much better performance than from any stock pedelec. And cost even are lower than a high end pedelec from flyer or stromer which use propretiary technology. My father spend a fortune just to repair his flyer battery.
I think we have all started off with basic lower cost kits only to realise that we should have went for the better more expensive system to begin with. So the mac will be a great choice.
The 8T on 60 volts gives me 40 mph and super torque, so the 12T, while slower should pull like a train up a hill even pulling a heavy load!
I will give you some good advice, cell-man will be installing temperature sensors in some of the macs, maybe by request, so ask him if he can do it for you. It will be the best think you could ever to to make sure you don't cook your motor!!!
I hope he doesn't mind me saying that but it's just one of a few things he is doing to improve the mac!
And ask cell-man if you can hook it up to thishttp://www.speedict.com/
Here is a thread discussing the divice which I think has great potential !viewtopic.php?f=3&t=22919
The trusty old cycle analyst is being upgraded to include temperature sensing and would be well worth getting when it comes out. So just ask Cell-man which one his temperature sensor would be most compatible with !
The speedict kit comes with a temperature sensor, but you would have to open up the motor and stick it to the windings yourself, but I strongly recommend it if climing hills while pulling loads!
Buy you won't go far wrong with a mac and cell-man's batteries!
Best of luck and let us know how you get on when you put all together, I would be interested to know what you think of it!
