Hi everyone ;-)
I'm new here , I am Jelle Vidts from Belgium. ( I love everything with wheels and a big motor )
I have just bought this real Stealth Bomber B-52 from 2013 , with only 70 km's !! :bigthumb:

But it's not all fun and games...
The battery was totally dead , so I send it to a professional rebuilder ( KWS Seuren in the Netherlands )
I upgraded it to the maximum = 40.5 Ah , stock is 18Ah ! ( offcourse 72V ) for the price of €1050 euro's.

But sadly , they say the motor is also dead.... A short in the coil.

Where can i rebuild this ? They say it's cheaper the buy a complete new rear hub motor ?
But I can't find any parts for this bike :cry:

any help is very welcome, thank you in advance !!

Kind regards,
Jelle

Fastjelle,

A QS 205 V3 motor will wake your bike up! 3.5, 4 or 5 turn and order a Nucular controller...... https://nucular.tech/ and you’ll hit hyper speeds!

Great find. Read up on maintenance for the V-box just in case.

Ok thanks a lot :thumb:

Will this QS 205 V3 stator fitt in my stock (oem) rear heb motor ?

Because my mechanic says that the dropout on the stealth bomber is 170mm ( and the dropout of the QS 205 V3 is 150mm ?
Total width is the same = 220mm

Will this QS205 V3 motor fitt in my stealth bike ?

Where is the best place / website to order a complete QS205 V3 ?

I appreciate this forum a lot :bigthumb:

the QS 205 even heavier than the stock motor plus you need to do some mods on the swingarm, the motor is wider than stock one.
Nah, I would skip that one unless I was riding asphalt only.

If you do mix and off road then go for a MXUS 3000, I had it on my bike. It is lighter and if you get a 4T winding instead if 3T, the acceleration will be better if you dont care about +80km/h speeds

So I am looking for a new rear hub motor.
An upgrade / faster motor would be great :flame:

Any help is very welcome, thank you in advance !!

Kind regards,

Note that since the OP decided to start a whole new thread for the same thing already being helped with in another thread, I moved all of those replies to this new thread. :/
