Does it use the KT controller or Lishui brand ?

The Crossfuse shouldn't be compered the dodgy Crossfire the latter is the awful HESC hub system and the former uses a Bosh mid drive.

John the mid drives are torque multipliers that can give some 300% power boost but they require the rider to press on the pedals harder. What I found with mid drive OEM brands was the continuous effort needed for the torque multipliers. With the cadence type one can happily just rotate the...

None of those are issues for hub electrics if the correct items are sourced to start with and none technically hard to overcome. As with any diy build one does ones homework first.

Yes EPJ road them for what they were designed to do in any and all weather, though I don't think they were quite made to be submarine like.

Yes don't square off the drop out seat completely otherwise you will over time induce metal fatigue at the corners, the radius needs to match the hub axle. One won't die due to compressive explosion like a Comet 1 but one doesn't want to see the wheel pass you.

Forum posters come and go but some who were quite prolific or regulars just disappear off the scene. Eddie PJ what ever happened to him, we know he became a product reviewer for one of the big emtb brands but just quietly disappeared. KirstinS suddenly just dropped off the scene. Tony aka...

Yep, SW has OCD and mothers that bike like no other. Except EddiePJ who no longer posts. edited spelling.

It is good encouragement and I don't disagree however your situation and the Ops could be very far apart in ability and stress on the heart.

I think a hub drive rear bike with pedal first option throttle is just the job, but don't think one will see an oem tourer ebike with one. I am assuming tourer means traditional drop bars, if that is the case having a tourer converted with a kit would allow a thumb throttle. One only needs to...

The Chinese are very good engineers, the joint appears seamless but is a fine pitched thread. Hence the keyways for a spanner to be used.

I think the screw joint is as arrowed. Vfr thinks it is this one. Which ever it is the keyweys are where the spanner needs to fit to add pressure/purchase to open it.

The keyways on the hollow axle/motor wire side plate have been mangled, a four keyway spanner is needed to undo the screw thread.

As I said Op needs to test out a mid drive tourer bike or a hub tourer bike and see how his heart rate goes, the flat might be alright it's the hills that might not be though.

Chinese generic branded hub motors, all use std wire connection sequence, any generic battery and controller. Mid drive brand frame/bike means no std motor mount is used with each only looking out for them selves. Hub motor can fit nearly any 9mm qr drop out. Never ever had an LBS repair or...

The OP has a heart rate issue , a mid drive means he will have to exert more effort to attain the 300% power available with good input pressure on the pedals. He will need to test ride a bike first and monitor heart rate vs effort to see if it is suitable. And can you tell us the kit problem...

Bosh are anti competition I wouldn't touch one of their bikes, though the other mid drive brands are all much the same.

Do you have PAS fitted ?

Bosh service centres don't carry parts all motors have to go back. Performance Line Bearings or try and bag a spares only motor.

Yes.
