it will work well just you crash faster spanner will be here end of week.

 

will change it then

 

if it went mac 1 id make it faster lol

You're doing the same as what the kids used to do on their mopeds, putting a bigger motor sprocket to go faster. There's an upside and a downside. Three teeth on 16 is a lot. Let us know how well it works.

 

It'll make it an equivalent of ten more teeth than I have for off road use, and my bike is still over geared running a 15 tooth sprocket.

Thinking about it, for my Swiss trip I might swap out for a 14 tooth set up. It'll be dry enough at this time of year, not to worry about the chain suck issue. Going from my current set up of 37.5 down to a 35, might just make a difference. Goes off to look..

My take on it is that you are just going to ruin all off road ability of the bike, and will be sacrificing battery life and ride length at the same time.

ill just change it back if i need to for of road use ect i bought it now so might as well stick it on there n give it a go

 

tho i am riding round with a broken arm so cant go of road to much just down the canal paths atm.

 

had a near miss with plod today as well down the canal sodding txt ing on his phone lol.

ill go faster tho tbh i just want to see how fast these things can really go ,target is get it over 50mph.

Blimey - 50 mph - you must be superman.

 

I have a 18t cog set up on my Xduro and have achieved 35mph down hill flat out pedals spinning.

 

The bike still handles well off road with the 18t.

 

On the Bosch motor for every revolution of the pedal the inner cog turns 2.5 times so:

 

18 x 2.5 = 45T on regular bike

27.5(wheel size) x 45 (front cog) / 10 (rear cog) = 123.75 inches (as per regular chain size)

X Pi (3.14) = 388.57 inches of wheel rotational travel for every pedal rotation.

/ 12 = 32.38 feet of wheel rotational travel

/ 3 = 10.79 yards covered for every one rotation of the pedals.

 

So if 1 mph = 1.46666667 feet per second.

50 mph = 73 feet per second.

2.25 pedal rotations per second.

 

An almost impossible (for me) cadence of 135 rotations per minute.

 

I will be very interested to know how you get on - best of luck.

I have taken delivery of the Badass v3.3 dongle today for my Haibike Urban, unfortunately it just scrapes on the spokes of the bike. I have read earlier in this thread that someone had the same problem and had to remove a spacer from the speed sensor. Sadly I cannot do this, as my speed sensor is as close to the frame as it can be. I have e-mailed Baddass but they've not replied yet, and unless they do a thinner version I think this will be a non starter. I know there is another kit which can be installed, but this looks too complicated for my very basic mechanical skills, does anyone know if there are any other alternatives or places which will install the dongle for me? I've asked two local bike shops and they've refused :-(

might help if you can post up some pics.

 

tbh no bike shop will help you with dongles unless you bought it from ebike shop.

 

can you change the back wheel ?

worth a try

Thanks soundwave, for the reply, I will get some pics on there.

 

Can't understand why bike shops won't help tbh, I'm happy to pay for the service?

 

I could change the back wheel, but I suspect by the time I'd changed both wheels it wouldn't be financially viable.

its because if they help fit it and you then hit someone on it tbh

i imo you could sand the casing of the dongle if its not that far off or just move the sensor closer to the rim then cable tie it on there.

Thanks again for the video and the pic, it's really useful.

 

Thats how mine looks on but, the spokes hit it, if it was just the wheel magnet I could move it.

 

When it's light tomorrow I'll take some pics, I'm also going to phone Badass tomorrow to see if they can help.

 

You've been really helpful so thanks very much

I did try and cable tie further down the frame, but the speedo then started to give random speeds and it still cut out over 16mph. I will try again tomorrow. Cheers again.

as long as the magnet passes the dongle you should be able to just move the sensor of its frame mount put the dongle on it then cable tie it back on the frame left of my pic.

 

will just need to try and keep it level that's all, worth a try

these are not that hard to fit tho id rather have the baeb dongle as you can remove it ect with less hassle.

well i left my bike in turbo mode and hammered it around all day with the dongle on and well it goes further than i even thought.

28 miles

Thanks for all your help, Badass have offered to send me this adapter FOC, hope it works!

Was your 28 miles in turbo mode constant assistance.?

yes went down a mode or 2 to stop but turbo all the way

Wow, the new 500w battery is rumoured to being released at the end of the year. I plan on swapping and that should hopefull give nearly 40 miles in turbo then

The 500wh battery is on the way.

 

Being Bosch, it won't be cheap - 800 euro was mentioned when Bosch launched the 2016 kit.

I agree, but I'm sure if you put your 400w battery on eBay, that would go a long way towards the cost!

Sounds like your wheel needs dishing away from the sensor a little.

Another very happy owner of the BAEB Bosch dongle.

Fitted to my Raleigh Motus.

Dongle was very close to spokes after fitting, but fortunately there's a spacer on the Motus that I was able to take off.

.

Anyone know why its recommended to rotate the magnet on spokes 90deg ?
