Selling my complete Hummie build. Parts and history:
- Hummie deck with Big Ben double stack enclosure - no holes in enclosure except for mounting hardware
- Kahua trucks and motor mounts - more than 1000km on those trucks, some marks are visible. Rear baseplate is Paris 43°.
- Bergmeisters - V1, more than 1000km on them, green slime inside tubes, no more flats
- 18T motor pulleys - less than 100km on them
- 60T 3D printed wheel pulleys - around 600km on them
and they still look great - 2x Maytech 6880 190kv motors - around 1000km
- dual ESCape with aluminium enclosure - around 2000km on this bulletproof esc. One esc shows correct voltage, another one ~0.5V lower than real value.
- 12s6p 30Q with Bestech D596 bms - this was first 12s4p and after around 1000km it was upgraded to 6p. Another 500km made with 12s6p. It fully charges, holds its voltage and I am getting range of 37-40km of medium/hard riding (my weight: 80kg)
- Flipsky VX2 pro - used for around 100km
- Riptide bushings and pivot cups
- Trampa BT module
Top speed with this gearing is around 53km/h.
Led push on/off button is wired out of baseplate in 3D printed enclosure.
Charging - jst 2 pin connector sticks out of enclosure. With board comes detachable charging port. I find this solution okay, because I didn’t have to drill enclosure. This connector removes some level of water ressistance. Charing up to 4A, because of thin wires, charging port and jst connector. If buyer wants, I can rewire it differently, as per buyers wish.
Some extras with board: spare belts, spare tubes, 2x Haggy 36T push in pulleys for kegels, Kahua original baseplate, new 3D printed spare pulleys, used 16T motor pulleys. I can add 12s 3a charger too, BUT it overcharges to 50.5V and I would not recommend using it. It will affect battery cycle life.
Things I think should/could still be upgraded:
- Aluminium pulleys - 3D printed works just fine, but aluminium are better for sure
- Different griptape, because this one is boring
- different charging solution - this one works, but it could be made different, probably more waterproof
I won’t part out this build for now.
Price: 1500€, shipping included.
EU only!
I’ll add photos of inside of enclosure soon!
I will do full maintenance this week, open up motors, do battle hardening if it’s needed and check all bearings.
