Go Faster Dongles! Here's another to consider

[stumpy150]

you are missing the point as the police will seize the fire blade for no tax insurance ect.

yes you are braking the law but the police will still see it as a push bike so none of the above matters.

if bosch cant prove a dongle has been used the police have got no chance of proving it

they can seize it as evidence - section 19 PACE then take it to bits and examine it or pay an expert to do the same.....

Yes well suppose there's plenty of money and loads of officers with nothing better to do.... My son was knocked of his bike last week... no one thought to check if his bike was legal, in fact police weren't really interested as long as the car was legal and he wasn't hurt.
He has had a bit of a battle with the drivers insurance company who never once asked if he had a dongle...

 

[stumpy150]

I think its only a matter of time until they start checking , especially when there is a serious injury involved, or if there is a suggestion that the bike is electric and going like the clappers..... I wouldn't risk it....

Money - that's what our council tax precept is used for -

Hi,

New here and don't want to tread on anyones toes but why are you paying for dongles?

There is a much easier free way to do it that doesn't affect your motors warranty and is easy to undo allowing you to ride legally to private land and then bypass the speed restriction for as long as you like then re-impoose the restriction for the ride home.

I will leave you to argue over legalities and voltages but this allows me to ride off road on private land with the land owners permission at 28mph (fastest I can spin my legs) with all the normal levels of assistance working fine.

The electric bike has a limiter that uses the bike computer to calculate the speed and restrict assistance accordingly.

This sensor

is triggered when this magnet goes passed and the speed is calculated

If you strapped another magnet(from a magnetic kitchen door catch in this case) to the pedal arm thus:

You can legally cycle to the private land where you have the land owners permission and then reposition the sensor so it is behind the pedal arm

Then, because your pedals don't turn as fast as your wheels the speed calculated would be slower than it really was and the motor would continue to offer assistance at higher real speeds.

In top gear with this set-up the indicated speed of 7.6mph might equate to a phone GPS calculated speed of 28mph which is quite rapid off road. Don't forget though, it is only an assist so you still end up knackered after pedaling like a loon to test it.

You have then simply remove the tape and reposition the sensor for the ride home with the magnet left in place for next time. All legal and won't affect your warrenty.

Once more I state - only for use on private land

Prey tell... how is this possible? My toes are pretty tough anyway

Bosch soon came up with a way of stopping that mod on early Bosch motors. Later ones give an error code.

Works fine on the 2016 Bosch cx motor equipped bike I bought last week.

I love inventive people! Hey guys we have another inventor!

 

[Gubbins]

Is it only me that doesn't know how this works?

 

[WorldClassAccident]

Your pedals rotate slower than your wheels.

This tricks the computer into calculating the speed based on pedal rotations instead of wheel rotations so thinks you are going slower than you really are. Therefore it keeps the assistance going.

Right... so that must mean moving the wheel magnet to the crank arm...... [emoji10]

 

[WorldClassAccident]

Yes - or do what I did and nick the magnet out of the kitchen cupboard magnetic close thing. Tape that to the pedal arm. That way you just move the sensor from next to the wheel - legal on road use - or move it near the pedal - unrestricted private land fun.

Did the earlier photos appear for you and do they make more sense now?

Yes, you can see details of doing this on my Panasonic support website, for that unit of course but the principles are the same:

i get a error code when i tried it on mine? maybe some others could confirm it now works again and save 100 quid on dongles.

 

[Gubbins]

Yes that makes sense, thanks for breaking it down....
.. I pay road tax so must own some share of the road, and as a private individual and road part owner I could use this on my bit of road..... my bit being the bit I am using at the moment.. ..
Seriously though. I don't want a dongle but I rather like the idea of being able to .. well see what it's like.... give it a try..

Make sure you tape the sensor the right way round. The same side should face the magnet so it needs to be flipped 180 degrees

 

[soundwave]

it must be the different software on the bike as mine will not work like that tho does seem to work on others and the Yamaha motor bikes.

just have to see if any others can get it to work on the new cx motor bikes.

 

[WorldClassAccident]

Try a bigger magnet or reposition the sensor.

The sensor it triggered when the magnet passes. There is no electronic intelligence in that bit. It is just a switch that sends the signal back to the computer.

The error code you get is probably saying the computer is not getting anything back from the sensor. It it the same error you get if you just remove the magnet altogether?

 

[soundwave]

its not that as Bosch did a software fix to stop you doing it so not sure why it now works less they missed it out on the new update??

you can also change the wheel size in the screen but made no difference when i last tried it on the peddle and just got error code.

with it like that tho what is the top speed b4 it will cut out? there are now dongles to remove any speed limit.
