Mac Motor Freewheel Options

[Degull]

Hi everyone. Was hoping to get some feedback on what types and sizes of freewheel fit on the Mac motors. I tried and a Sun Race 9spd freewheel last night and there was not enough room on the drive side. I could use some spacers and dish the wheel but I was hoping that where some other options. 7 speed is good but it really limits the choice of shifters. Any suggestions?

It's a short list of one.
You will need the smallest cog to be as small as possible, which is an 11T
Only DNP Freewheels offer this.
The most speeds that will fit a 135 mm drop-out with that motor is a 7-speed..
DNP 7-speed, period.

Unfortunately the best option is the DNP 11T-34T or 11T-32T freewheels.

Methtek.com has some.

7 speed dnp works great.

Only a small spacer and a DNP 8 speed works. Oh if the swingarm is alloy use the 7 speed, don't try to stretch aluminum!

Not bad with 9 speed shifter and 8 derauler. Shifts good but has one missing.

I know many say you don't need but the 11t since it's powered. I like to be able to pedal at differant speeds other than WOT. So using 8 or 16 of the 24 works great for other than full throttle.

7 speed it is! I agree that 11t would be the way to go. I still like to pedal my bike and there will many times when I leave the battery at home. Thanks.

Both Shimano trigger shift pods, and SRAM twist grips are available to bike shops, from J&B. Any bike shop can order from J&B, if they don't already have them in stock. These will work with any Shimano rear derailleur, through current 9 speed, and Shimano compatible SRAM rear derailleurs. The 7 speed shifters available now are not the top quality ones available when 7 speeds was new, but they work just fine. The important part is to used plastic lined, derailleur specific, cable housing, and a good quality rear derailleur, not steel and plastic crap, like I see on many e-bikes. If you are actually planning to ride this like a bicycle get a real derailleur!

I'm on the hunt for some old school mountain bike thumb shifters at the moment. My rear derailleur is an older shimano XTR. I agree with you. I don't mind riding a 7 spd as long as the gears work flawless. Installing good gear cable and a quality rear derailleur will make up for the gear count.

I can't use the rapidfire type shifters because of the switches on my throttle. It has a cruise and three speed switch that get in the way. Over the bar thumb shifters make life much easier.

Just checked. I didn't know they still made these.
