The 5 inch motor; no longer a myth!

For years, the community has been eager for a complete 5-inch motor solution. The days of cannibalizing Hypercores and mismatched hubs and rotors are over. Introducing the Superflux 5 inch motor — the 5uperflux.

With a decade of experience perfecting the original 6" Superflux, we received countless requests for a 5 inch version. We took all the magic from the 6" Superflux, shaved off weight, refined the aesthetics, and after tens of thousands of dollars and a year of prototyping and testing, we proudly deliver exactly what the community asked for:

A 5" motor that is small, light, yet mighty! It outperforms competing 5" and even 6" motors from other brands, delivering smooth rides and extreme power while maintaining a lightweight setup with cushy tires.

Features & Improvements:

  • CNC/Billet motor covers: Getting good thermal performance from a small motor isn't easy. All 5uperflux motors come with billet motor covers for enhanced thermal performance.
  • N48SH magnets: One of our secrets was to use the highest grade magnets, the SH magnets, unlike the M magnets are built to withstand temperatures up to 120 degrees Celsius!
  • Genuine NSK Bearings: Superflux never compromises on quality, as always we use the best and only original NSK Bearings.
  • New and Improved Axle Blocks (more thermal goodness): Replaced the original FM style axle block with improved thermal performance and enhanced aesthetics. Axle blocks are sold separately: Funwheel Axle Blocks for Funwheel builds, GTFO Axle Blocks for GT/GTS builds.
  • Highest Amperage Plug-in Single Connector: Uses the same trusted, industry-leading connector as the Superflux 6.
  • Ground-breaking Performance: Available in two versions — High Torque (HT) and High Speed (HS). HS version is ideal for high-speed enthusiasts with battery setups from 15S to 20S, perfect for GT/GTS builds. HT version suits higher voltage builds (20S+) and riders seeking more torque, punchy acceleration, and hill-climbing efficiency.
  • Power: True 3000W+ motor — the most powerful motor in a compact package.

It's a great Motor but...

I was really excited about this motor. I think this motor would work well for riders that don't ride trails crazy hard but I have had thermal issues and so have others that I have spoken 2. Others also report very different KV on detection and claim they don't have overheating problems. So Not sure. I have been tweaking my motor config to try to find a cooler config but It's been a struggle.

5uperflux HT is amazing

With it you get all the good things: power, tire softness and coolness. The Okonimiyaki of motors!

Constant overheating

If you don’t ride trails aggressively this motor is great. After 35 miles of trails it’s overheated 3 times. Definitely not as good as the 6in.

Hello! This is not OK. We want to make sure you get a trouble-free motor. Please reach out to support@fungineers.us and they will fix it! Thank you :)

Great motor!

Coming from an OG Pint, this motor + LR Drivetrain is in a different league. Plenty of torque for steep hills, I haven't seen duty cycle over 60%. I’m running it with a 5" Pioneer and have been really happy with the combo.
