10 speed freewheel on DD hub motor? It's a 10 speed bike.Any known issues?

[James340]

That would be unusually heavy. Link? Maybe you mean pounds? 6-6kg would be average, Grins all axle is 4kg.

That's the package weight.She didn't know motor weight.The 1000 watt motor I have is very heavy and with the supplied 48 volt 28 amp controller never got hot.I put a 40 amps controller and it gets pretty warm

I got it on sale for $119 USD.Total cost $289

I wanted a cassette motor but the price was 4 times what this motor cost.

Hm, what brand is charging such a high premium? for most motor makes, this difference is more like $20.
If you go to a 7 speed freewheel, prepare to change out your shifter, chain, maybe also derailleur..
Not a good option.

So much more cost effective to get the cassette version of the motor and subtract 1-2 gears from the cassette.

Except if the free hub wears out or breaks, sourcing replacement parts might be difficult. When my freewheel wore out, it was a simple swap, and all of the moving parts were replaced.

It's not challenging to find bargain ebike parts at all. The ebike market is 99% this stuff, and 1% quality goods.
The problem with bargain basement is that the brand names are almost always changing every year, and the vendor worked hard to make sure you cannot figure out how to fix the part. That's responsible for most of the questions here. And there's no feasible way to support that stuff, so why cater to it at all.

The cost of a motor with a cassette is typically ~$20 USD.. not 2x or 4x...

This is true.. but 7 speed drivetrains are kind of an endangered species lately and that's a problem.
If you want an 11T low gear, you have to buy a shoddy quality freewheel like a DNP, unless you get very lucky and find yourself a decades old Shimano megarange.

Pick your poison!

Agreed. But I’d kick myself if I had to replace a good motor because I couldn’t replace a “bicycle” part. Going that direction, I’d devote some research on availability of parts when needed, and that would likely narrow the field to something like Grin, and maybe a small handful of others.

This is a popular motor and I have one like that. Ignore the 10-speed stuff if you didn't get the cassette model.

I agree that it's weird, the price was very similar for mine. I got the cassette model and they even included the cassette.

I disagree. You won't need 10 speeds with the power it can pull anyway, and the parts for 7/8-speed are cheap and plentiful. 10-speed MTB sets were always inferior in durability and robustness anyway, and with a motor you can skip a lot of unnecessary pricy parts. I put up to 2200W through mine with no significant heat buildup.

I have worn out a pair of DNP 11T freewheels, installed at same time on two bikes, Pawl started to slip, Perhaps if I had soaked them in solvent and re-oiled, they would still be good, but was dismaying to see the first one spin without catching, I replaced it and then cursed and replaced the second one a few months later. The kicker is they cost 2.5X more than a very reliable SHimano 7 speed.

Since then, my pedalling style has been to spin the pedals in a bigger gear, like 16T. The motor, if it could, would thank me, Really don't need an 11T to ride at bicycling speeds.
