Hi Steve,

 

I've got it installed on my Haibike with the Yamaha motor. I've been using it for several months now and it works great. It was very easy to install.

I think you mean that you know somebody with it fitted to a Haibike and he tells you that it works great.

Thanks for the info jkz, any probs with the display and do you turn it on and off with the light switch?

Dave it's not for me it's for a mate, wink wink.

The display works normally. It reads the correct speed. Yes, it turns on/off with the light switch.

We had one forum member who boasted on the forum about his go-faster dongle. Then, when he needed a warranty repair, the dealer, who reads the forum, told him that he had invalidated the warranty with the dongle.

How come you can buy a bike from Martin with a dongle on then?

been asking that since i joined he will not reply to the question as no other dealer will honer the warranty if a dongle has been fitted.

 

tho as the dealer cant tell if one has been used or not its best not to post on here that you have one

 

tho at the end off the day you are just using the motor as it was designed for.

 

i have never had a problem motor or batt wise.

Well I got my bike from him so I will just ask him and then go from there

it will be his dongle you will have to fit tho and there 150 quid i doubt he will let you keep the warranty and fit a 3rd party one.

Yep I bet you are right.

he might not also let you fit it and then that gets expensive with the trip to the shop as well.

 

tho it is simple enough to do it ur self just see what he says

I may just hang on till my warranty is out

its up to you tbh but i doubt you will have any problems easy option is a badd ass dongle like i have that just slides over the sensor.

 

that way you dont even need to open the motor case just the speed will be half on the lcd.

 

these days i dont even bother to look at it tbh.

 

the difference with a dongle is night and day it will be like a different bike

Sinner repent ye!

 

It does sound very tempting though doesn't it?

I have that dongle fitted by Martin, very happy no issues (touch wood). i suspect Martin would simply remove dongle and claim against Bosch as they won't know. Other option, you just remove it if you need to claim against Bosch.

Either way dongle i have assist's to 31mph, but now hearing of some dongles that assist into +40mph?

the asa dongles remove the limit completely there is no cut off.

must say I'm tempted, but is +40mph safe hmmmm

Sorry, when i mean safe. I'm reasonably sensible on bike knowing what speed i can go and where, also my bikes brakes etc can handle +25mph, but +40 hmmmmm

the faster you go the less it will assist but still pull full power these things were never meant for out right speed.

 

you might get it to 40 with a massive front sprocket 20t plus but thats not going to help you up a hill so you have to think off speed how far you want to go and any hills you have to climb.

 

the asa dongles also show the right speed.

Thanks, i've got a 18t on front (haibike one). The connex type one above i've tried 18t and it was so close to casing the chain damaged the motor case.

i had the same sort of problem with them as well with a 19t one as it was so thin but with that you should be fine as its 25t and it is massive.

 

i found when i used it i could feel the motor grinding in some gears so sold it.

 

 

i now have the dual kit so have 18t and 15t

Nice bike!. You use the 15t, as i've got a 42t cassette the 18t at front seems more than enough for steepest stuff.

 

Also, did you say you had a dongle fitted?. I do, max 31mph. Looking at ASA, peartune and RS, but only looking as they seem to offer even further speed assist.

i have sram 11 spd so 10-42 and with the 18t can get near the cut off speed off 35mph with the badass dongle but max effort required.

 

for climbing hills you want a smaller sprocket at the front just going back down you spin out as why most come with 14-18t sprockets it just depends what you want the bike for gearing wise.
