Speedbox 2 for Yamaha system

Just been reading up on the speedbox 2 for the Yamaha system. Looks very impressive that you can turn it on and off with the light button, plus all the read outs are not affected. Can someone tell me, are these speedboxes etc good for the motor? Do they damage it in any way? I'dlike to get one but if it's going to trash ordamage the motor, I'd think twice!

I have also been considering one of these as my bike has the lower speed restriction of 25k.
If it had the higher one I wouldn't bother.
I would imagine it would void the warranty
I was hoping someone would come up with some software to reprogram the computer to the higher setting.

Here in the UK the max limit for electric bikes is 15mph. From what I understand it's higher in other countries, so if that's the case, these bikes were designed to go faster but the UK models must adhere to the 15 mph limit. So 'unrestricting' the motor system in theory shouldn't affect the warrant????

Can anyone put me right on this?

Or do you just buy a different lcd control panel from a country where the bike is not restricted and have the UK bike unrestricted.

I'm in NZ & have a Euro spec restriction like you have.
The US sold bikes have a 20mph or 32k restriction.
I would be quite happy with that.
Any faster than that you would have to change your gearing.

I believe the computer is in the motor area, not the control panel.

I'd be happy at 20 mph. In 10th gear on the flats, my pedal speed is around 17 -18 mph which I'm comfortable with, if I want to cruise with motor help I have to drop to 8th gear, at the same pedal speed that gives me 14.8 mph. It's a shame you couldn't adjust the speed yourself to suit as 20 mph would be fine for me. Either way I think the bike is great, I just want to know if by adding a speedbox, will it damage the motor in any way. I don't even know if it will pull to much out of the battery!!

I live in US and have 2016 RC. i ordered one, installed it and it lasted for about 5 minutes ( not even off the stand) Installation is super easy, seemed to work in MPH. uses the light button to change. Only issue was it failed in only 5 minutes. Patiently waiting for my replacement to arrive.. Will advise as soon as i get it installed. Why i got one. I found that i could pedal at 20mph depending on terrain in either the 32 middle or the 42 / 44 large chain ring without too much effort.. coming out of . a corner onto a straight its like hitting a headwind.. 18,19 then 20 ish and boom, instant slowdown. I believe the ideal speed for the bike is 25MPH ( cadence is they next limiter on a PW motor). I would love a PW-X motor with a de limiter.. the speed would be amazing.

Works well.. Speed is wildly inaccurate ( speedbox tells you this will happen). Can easily pedal to 22 / 23 MPH on flat. Tried down a hill and could still feel the assistance at over 30!

Any product which is plugged directly into the motor is likely to cause issues in the long haul. I have seen implications of the battery a few times.

As I am sure you know, all speed tuning devices are strictly disallowed by each bike's respective manufacturer and would in-turn void the bike's warranty. Although, it may be difficult to prove the use of a tuning device in this situation.

Ordered one yesterday, been told the new version gives correct speed etc, also that it won’t affect the motor in anyway, it just doesn’t stop at 15mph. The US version of my bike is restricted to 20 mph so the motor is ok past 15mph, it will just run the battery down in less time! One bonus if I’m out on my own I can turn it on, out with the wife and leave in std mode!!

Will do a write up on it once I’ve tested it.

Ok mad badger, I’ve got a Haibike 2019 and just purchased a Speedbox 2 it’s labelled as a 2019 and my bike is a 2019 bike with the side display, I connected it all up correctly but it didn’t work.
Nothing nada...
Spoke to the ebay guy who didn’t have a clue. He was nice enough and said returns are not a problem but it doesn’t help much.
I’m not wanting 50mph or anything but I ride a Cannondale badboy and sit around 23mph on a run that I do , just want a but more than 15 on the way home with wind in face etc.
Commute is 4miles so battery range is unimportant a long run out is 19km round trip
There is no reply from SpeedBox.
Any ideas.
Which display do you have.

Hi there, I have the old display (mobile phone style) my bike is a 2015 so it’s the older px motor. I connected mine as the instructions and it work as it should. Gives the wrong info in mph mode but it’s correct in kmh!! If I’d have known this I would have gone with a different system. Having said that it works ok and assists me all the way to flat out, well as fast as can pedal anyway.

I would send it back for a refund if I were you. I purchased mine directly from speedbox and the guy I dealt with seemed very good. I saw them on eBay for a few pounds less but I’d rather buy from the manufacturer at least that way if there any problems you can go back no problem. If you followed the instructions to the letter I can’t think why it wouldn’t work. Does the display change at all when you activate it? If not it’s either a wiring fault or the unit is dud. But the plugs can only go one way, I’m saying that as it did on my installation, foolproof really.
Send it back and order one from speedbox, I’m sure there will be faults as there are in all electronics, but when it’s working it’s good!

Nope nothing on display at all it’s plugged in right, I only paid £101 for it with an ebay voucher

Only done 3 miles on odo but it says in instructions 1 is enough there seems to be a few versions for the Yamaha but I dont want to just keep on trying different ones, one thing I did notice on my brand new bike was that the large square plug had a damaged retainer even before I had touched it 🤔 I’m a bit precious about stuff like this and I am very careful looked like someone had been in it beforehand. Oh and I’m like 19 stone and the forks are almost fully compressed, static with me just sat on bike I’ve turned preload to the right about 20 times and they don’t stiffen up at all, may need to upgrade them lol

I’ve read somewhere that you need to put it into Kmh mode for it to work? Dunno how to even put it in kmh mode lol, I’m waiting for a reply from speedbox

Is it second hand? Mine was £135 delivered from the manufacturer. It’s possible you have the wrong type. If the plug looked damaged I’d send it back and get a refund mate then contact speedbox. When you go on their site you just click on the picture of your display and it takes you to the correct unit.

Only the early px motor like mine only works correctly in kph. The later versions work ok in mph

Just read that you only have 3 miles on you odo, disconnect the unit and run it for 20 miles then reconnect.
