Oy oy, ere we go again!!!

Better read the "new name for the forum thread"

 

If you use the word dongle, you'll get done by the dongle police!!

Hi Electric daz

 

If you do a search on this forum relating to dongles, you'll find that their use is a very contentious issue.

 

This explains the initial response you've received

i have a dongle of doom

I have had a quick glance around the forums and I understand both sides a bit more, I love my new ebike but I regularly hit 25-30mph on my standard bike but the issue I find with the assist system is after the cut off point it can be a heavy sluggish bike on the flat which then makes me slower than I am on the standard one

i have a dongle of doom

Is it a good reliable addition to the bike?

never had a problem with it should get 5000km from 1 batt and there 7 quid.

 

cut off speed is 35mph

The Badass dongle does what it says, it removes the speed cut off.

 

It will make the bike faster overall, but don't get too excited.

 

There is no 'tuning' or extra power.

 

The motors are built for torque, not speed, so the assistance tails off the faster you go.

 

Being a fairly strong cyclist will help you get the most from the dongle.

 

Fitting might be a problem.

 

Some new ebikes have the chain stay sensor mounted close to the spokes or rim, leaving no clearance for the dongle.

 

Badass have a couple of brackets to sort this, but remounting the sensor can be difficult if there is no slack in the cable.

 

Hopefully, yours is one of the bikes that needs to modding.

 

Regarding your riding experience so far, I've told a few fit roadies over the years not to get an ebike because it will only slow them down.

 

I'm sure each thought I was being obtuse.

Is that the dongle of doom Mk 7 sw?

no 3.3 but if you ask they will do a 3.2 and the cut off for that is 75kph

 

you just cant peddle that fast, or i cant anyway lol.

Anyone tell me the best place to buy a dongle for a Bosch CX assist mid drive system (is it only badass.com)

what bike do you have as some cx motors wont let you put a bigger sprocket on the front.

 

if you want to go over 30 mph then you will need a 18t on the front.

Cube Reaction Hybrid HPA Race 400 29er 2016, but not looking to hit 30mph just happy to get to 20 and on the mad occasion 25mph with the assistance

looks like the egg shape case same as mine so will be ok.

 

you just need the spanner to remove the lock ring and a crank puller for the peddle arm.

 

this site sells the spanner and a dual front sprocket 16t-18t

Do I need to change front sprocket, I have 11 cassette on the wheel and am only looking for an average of an extra 6-10mph increase?

if you have 14t atm then yes as i have 16t 10-42 at rear and can get to 30mph

 

and im putting as much effort doing that as on a normal bike.

Thank you for all the info you have been a great help, I will be taking it all in and making my decision in a day or 2. Again many thanks

you will need the lock ring spanner some time to change it anyway so best get 1 as not good idea to try do it with a hammer and screwdriver. new 1s are 12 quid.

 

id also remove it now and then as muck builds up behind it anyway

 

crank puller 5 quid and just takes 5 mins to change over sprockets.

 

I tried to buy a badass dongle from * but the site would not let me pay and they have not replied to email sent anyone know of any other places to purchase said item??

 

[Admin: Links to purchase dongles are not permitted. Thank you]

did you try and phone them?

 

you can get it dir from bad ass if you use paypal

I will try tomorrow, my problem is I'm a night worker and am usually asleep during opening hours so like to do things online (wife will not let me use our PayPal as she is sick of me spending money on cycling stuff)

I'm only reasonably fit and in my late 30s, but the badass dongle is more than fast enough for me on an otherwise standard haibike sduro trekking.

 

On flat with no wind 30mph is fairly easy physically, 35 for short bursts, 40 if really putting in a lot of effort.

 

Even though 30 is fairly easy, I only feel I can go that fast safely maybe 10% of the time and my average speed is 15 despite a fairly open commute. Braking distance / visibility are the main limiting factors.

 

I've only been overtaken once by a bike in months. At 30mph a more confident Kalkhoff whizzed past - am guessing at over 40mph without much effort so guessing a bigger motor.
