After looking over all the ones on the market, i've decided to make my own in the future. Something like a rans fusion but with rear suspension.

Time to make a frankenbike with a walmart bike rear end, lol
Efficiency is everything :bolt:

My first major build: 1.6kW 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w @ 4kW on a Turner O2 full suspension.
The monster scooter: 20" eZee on a Cannondale Semi Recumbent.
Whipper-snapper: ? on a lightweight BikeE Semi Recumbent

Yeah, AW, if you live in the sand like we do, you do have to pour motor oil through that freewheel pretty often to flush out the sand. It might be just oiling them at all that makes the old crusty one so much quieter.

At the flea yesterday, I saw a 20" mtb with a rear shock. I thought hmm, just what Id need to put a rear shock on my re bike.

I've had good luck with Phil Wood Tenacious lube on freewheels. Drop it on the inside diameter of the lockring by the smallest cog, right where the splines for the tool are. This side works better than the backside where the threads are. Put a good amount, then hold the back end and spin it around a bunch of times, while pointed upwards (small cog up). It should begin to get quieter as the lube wicks down into the internals. Phil Wood won't dry or gum up as far as I know, and it's fairly waterproof. Might leak out a bit if you applied a ton.
There are two types of people in this world.

I had a very similar Giant Revive DX conversion a while back, with a front 9C on it, and kept the rear end cassette and pedalling capability. You would loose your front disk brake probably if you did that. I replaced the stem with monkey bars. The twitchiness was substantially reduced with the motor mass on the front, and a rear battery that seems better balanced against the massy front motor than your configuration. It was a very nice comfortable ride, not the greatest for pedalling given the geometry, but very fun and unique ride.Widening the handlebar helps to reduce the twitch offering finer control of turning on the contact patch. The rear rack was a decent spot for the battery, with the hub motor on the front. So I think your bike is tail heavy, a bit twitchy, and no pedalling offered. This could be improved.
