I've asked the seller twice now for information, all I get back is "I can assure you that it works" I was intrigued to see how it works as its states "no wire cutting" and "no batteries" hence I was thinking it must be a mechanical device.

 

The more I think about it the more I think its a scam and I certainly won't be risking my money on it!

 

I think i'll end up with a badass typ3.3, but I am keen to find a mechanical solution to the problem! mmmm

There isn't a mechanical solution. You have to reprocess the speed signal.

If you could find a way to 'hide' the magnet every other revolution would this not work? Surely the speed sensor would then think the bikes going half as fast as it actually is?

This made me smile, well done

Yes, that would work.

The magnet would need to be fixed to a frame mounted star wheel of some description. A 360 degree rotation of this star wheel would pass the magnet over the sensor.

 

A small peg fixed to one of the spokes would knock the magent wheel round by say 90 degrees for each revolution of the road wheel.

 

Every 4th rotation of the road wheel would move the magnet past the sensor.

 

It would work but requires someone play around with brackets and bits of plastic to get the design sorted.

 

Bit of time and a few quid, so not such a bad idea.

I have just received the badass dongle for my yamaha powered haibike and it makes a huge difference, so easy to fit and if it needs removing I guess it will take less than a minute.

 

I know it only eliminates the motor cutting out at 15mph but seems to give a better power delivery not sure why.

It could be that the motor torque just matches the gearing better at speed.

 

Don't think for a minute it's a flyer just more relaxed riding and mostly in the medium setting. High for hills mmmmmmmmm

I just installed mine too. what sort of speeds are you getting?

 

I can't seem to get over 40km/hour with the gearing on the sduro.

 

Wondering what options there are to get another 5km an hour out of the sduro.

You will need to go for a larger front sprocket.

Look for martin's postings here. Though that's if your in the UK.

I use mine mostly off road so don't need higher speed but would be nice some times.

Fairly sure you could go for a double clanger looks like all the fixings are on the Haibike.

For your info just over 40mph down hill

Don't forget that cruising above 15mph will consume a lot more battery.

I think it could probably be be done mechanicaly.

 

I see a pawl and gear arrangment that exposes the sensor to the magnet every third revollution or whatever the pulse ratio is for the dongle.

 

Probaly cost more than the bad ass solution though. It would need precision parts that can withstand the mud and extreme conditions. Maybe Shimano could get involved?

Though that's if your in the UK.

I am in Australia.

You mean 40km??

 

If not that is one crazy steep hill

That is 40mph on my cycle iPhone app fairly sure it's withing say .2mph

Have you viewed the badass site to see if they will ship to Australia

Ps tonight's top gear comes from Australia though they seem to be missing badass dongles on their cars

Ive already got the badass dongle.

 

The gearing on my fullnine sduro doesn't allow me to get much over 40km/hour. My legs are doing a roadrunner even at that speed.

 

I amazed that you are getting 65km/hour!

 

Are you pedeling at that speed?

You won't get that speed by pedalling as you know my haibike only has a 9 speed and mountain bike gearing, steep hill is required though not a lot of effort.

I think if you wish for plain out speed with the dongle fitted you either need to increase the size of the front ring gear or go for a double clanger arrangement.

 

Looks like the sduro range have the fittings ready to accomplish this.

 

I must say I'm delighted with mine as is, though a higher final touring gear,between trails would be nice, maybe splitting hairs here.

 

With the standard gearing mine cruises at 22mph in MED without too much effort, slightest hill and you would need to go to HIGH.

 

I feel most cycling on road is at between 15 and 20mph and the dongles just make it that bit easier without it becoming a motorcycle.

I can pedal my bike to 39 mph downhill, that's above any motor assistance I have.

You can pedal your Sduro at that speed?

when does the badass dongle stop assisting you does any body know

I think it's x3 15mph so in theory it won't cut out until 45mph?

There will be others much wiser here who will know the facts.

 

Fairly sure that 70nm and 400watts are not going to be much help over 40 and mines not geared for speed.

 

But it's great FUN all round at any speed...........four punctures in just over two weeks is irritating.

go tubeless not had a puncture in 2 years so what your saying is its always assisting you must kill the battery

Not thought about the battery.

 

Tubeless maybe worth considering. Three punctures from thorns here on leicestershire byways and bridle paths tow paths all thorns and one pinch type from down hill rocky path.

Not sure tubeless would have coped with the thorns as they get though motocross tyres with heavy duty tubes occasionally.

Depends what you mean by 'kill'.

 

The Bosch system is always on, so you are always using the battery, whatever speed you are doing.

 

Going fast uses lots more juice - that's an ebike truism.

 

The battery management system is designed to prevent harm to the battery.

 

It's not bypassed by the dongle, so using a dongle causes no harm to the battery.

The gunk in the tyre should solidify and plug any holes from thorns. I'm running Slime in my inner tubes which has worked for me so far but I am seriously considering going tubeless as I am not confident at all about dealing with a puncture on a mountain top on my own in the middle of nowhere. Everything I have read about tubeless is very positive, with the first mountain biker I met locally recommending Stans No Tubes.

The only experience I have with tubeless on bikes was attempting to help someone with a deflated (tubless) tyre.

We end up having to put a tube in.

 

If I remember correctly, motor car tubless were not that good in the early days, most of us sticking to tubed tyres. Seems most alien now.

You can pedal your Sduro at that speed?

 

No, my hybrid.

when does the badass dongle stop assisting you does any body know

It cuts out at 50km/hour
