Re: Something other than a hub or mid drive

2.7kw with a custom made 350Wh battery. Made a 2 stage reduction. 3:1 first stage, 5.4:1 second stage. I made the small sprocket removeable so I can swap between 9, 11, and 14 teeth on the fly. Current gearing gives it a 31mph max speed. Done in just over a week. Very well done :thumb: Maybe next b...

Re: Lifepo4 battery needed for qs138 70h v3

Can anyone suggest a battery supplier so I can use the faster controller? What is the size of the battery box you're able to fit?: Battery box size.jpg If you can fit 20x22x65cm (8x9x26inch) then you can build a 20S2P battery out of the LG NMC pouch cells that member Tumich is selling: https://endl...

Re: Electric motorcycle for asphalt and longer trips

I would think the Super Soco TC Max is the better designed and better riding bike. Looks a more refined product with a mid drive motor.
Why change the battery right away?

Re: New motor, USA made: Optibike Powerstorm MBB

Hype, but interesting https://electrek.co/2022/09/12/optibike-2500-watt-electric-bicycle-motor Wonder if adaptable for a multi-drive cargo bike? Or maybe use the whole OTS bike and adapt? Or with a trailer? Looks like a lighter, much weaker and more expensive version of the Cyclone Coaxial motor ki...

Re: My custom frame full suspension long tail dual hub cargo bike

How would you design? At least use some triangulation (red) in the frame where the weight will be. Now it looks like a folding mechanism without the hinges. And use bolt in triangulation where the battery pack is situated or make the battery box a stressed member. The swing arm can be a simple, old...

Re: Can't choose motor

OwbtIvpeTE4 Look from 3:36min for a size and weight (double) comparison between the QS138 and QS180. You want the QS180 90H to be able to have the most chance of keeping the motor from melting at 30kW for any serious amount of run time. Read through this thread of member Nuxland and see the evoluti...

Re: My custom frame full suspension long tail dual hub cargo bike

Why such a complex rear suspension design for a cargo bicycle? And not just two simple shocks on a swing arm like an old motorcycle?

Good that you are still able to do these runs. Too bad it isn't yet at full power. Any word from Scott Drive about your issues?

Sounds very interesting. Are you looking for a different inverter to increase the power?

Re: Electric standup jetski build

Parallel string? Like another row of batteries to increase AH or is that a wiring thing? :) Yes. I don't know how your battery pack is built but adding extra Ah will "stiffen" the pack leading to less voltage sag (keeping the cells at higher voltage and less stress) while being able to pu...

Re: escooter diy steering geometry problem

With the Dualtron you posted I suspect that when standing on the deck that the front suspension will be compressed and the front wheel axle will rotate/move forward. So the "meeting point" of the black and red line will be a lot lower making the "trail" shorter. And the Dualtron ...

Maybe add another parallel string to the battery pack so the voltage sag is less and riding time increases?

Re: NEW QS 165 MOTOR

This is also good news because VESC controllers work with these encoders. Great that you were able to solve the noise issue. And if VESC controllers work with the encoder on this motor then the new Flipsky 75200 could be a nice match: https://flipsky.net/collections/electronic-products/products/fli...
