New Bosch CX 2020 derestricting

[Ronald B]

Hi all,
I am looking for a new ride with the new CX motor in it.
But Would want to derestrict it.
Cant find any info, so any help in the good direction would be great.

Thanx Ron

I thought the new 2020cx was designed to stop all attempts to derestrict it. Maybe there will be a magic add-on box in the future but i don’t think it’s been invented yet.

Does the new Bosch motor uses GPS to compare the actual speed with the speed registered by the magnet? If not I guess the mechanical LSS that jd_3d could work.

 

[Doomanic]

AIUI, you can’t use the old magnet on the crank method as it matches the cadence to the pulses and errors out. Three errors and it’s a trip to the dealer to get it unlocked.

 

[Matthew87]

That was not the method I suggested. I meant with the LSS that the Levo guys use.

 

[Doomanic]

I know that, I was pointing out that the old method probably won’t work.

 

[Doomanic]

The LSS solution is probably the best bet if the magnet is on the disc. If it’s on the spokes it may be a lot harder to get the sensor lined up.

 

[Matthew87]

The magnet is on the disc on my bike, but I just wonder if anyone know if there is a GPS on the Bosch motor that recognises if the bike moves faster than the magnets register.

I been following this thread on endless-sphere, a guy as has got a VESC controller running with his bosch motor. A VESC is an open source fully programmable controller. Looks like he got it working with pedal assist and throttle. Perhaps someone could commercialise this?

I'm pretty sure all ebikes use three phase sensored motors. Pretty standard stuff, should still work

 

[David0208]

I can say from my experience of the new Bosch motor..... you won't need to de-restrict it as the new motor completely disengages and there is no noticable drag and rides like a normal bike.

If you still want power after 25kmph ... then as always there will be a way.

It seems there is deristrictor available

Anyone have any information about this? Does it work?

 

[kntr]

How is the Gen 4 motor? Has anyone ridden it?

 

[David0208]

How is the Gen 4 motor? Has anyone ridden it?

It's great..... almost no drag when motor is off. Big differences between each setting of eco, tour, EMTB and Turbo.

 

[kntr]

How does is compare to the Brose? Im selling my Levo.

 

[Matthew87]

Can confirm that it is now possible to derestrict the new Gen4 motor with the Speedbox 3.0. Tried mine yesterday, only up to 60 km/h though. Should give assist up to 99 km/h.
Haven't done a long ride yet as well, so might wanna wait for that to confirm it works 100%.

That’s quite fast. Was it on a flat road?

No, a small hill

What Bosch Gen4 equiuped bike have you fitted on?
What display does your bike have?
How easy is the set-up and activation?
Any waiting at the end of a ride to allow for the computer/electronics to make calculations?
Cheers

A Whyte E-150 with a Purion display.
Installation takes 2 minutes.
Yes, you should wait with turning off the bike according to the instructions.

Does the walk mode still work? What all is affected?

 

[Beekeeper]

Wonder (hypothetically speaking) if an average Sunday cyclist on a road bike in Lycra would still race past you on the flat or would the tables now be turned

 

[Matthew87]

Does the walk mode still work? What all is affected?

Yep.

 

[Tribey]

Yep.

I though as the 'walk' button activated the Speedbox, that would prevent you using walk. I don't use walk, so it's not a loss for me.

Got the speedbox 3 fitted on my cube..
Only big smiles on my face when I blast through the trees at high speeds.
Works like a charm.

 

[Beekeeper]

How I feel when I hit the 15.5mph limit on a Bosch Gen2 can only be summed up in pictures not words....

 

[Doomanic]

I found that the old motor tailed off from 15.5 to about 17mph and then was in full on treacle mode. The 2020 CX stops assisting dead on 15.5mph but is less treacle-like over the limit.

How hard was it to install?

How easy to take off if warranty is needed?
