What is volspeed V4?

[mastakilla]

I have seen this on a couple of sites. But no description about what is different than V3

Interesting how they have now added the ability to mess about with the profiles a bit. And a max limit of 28mph is still more than enough for me. Hmmm

Hi there,

George from Ebiketuner here, did you decide to go ahead with the V4? TLDR they've improved the anti tuning detection and also made the it plug & ride.

Hi George, no I havent yet, still very inteterested though. Its only the possible issue with a 504 that bothers me, nothing else. I didnt know anything had been changed re the anti tuning detection though.

Now that the max speed has been capped at 45kmh it's extremely unlikely that you'll get a 504 error now. Most of the time these errors happen when people use their bikes for commuting and consistently ride over the limit.

I have around 250 miles on Volspeed V4. No 504s and it is mostly working as intended.

However, I am not getting the advertised speed out of it. I am in US and I set it 27.9 mph as top speed, but the motor is still cutting out around 25. It is an def improvement over stock where it cut out at around 19 but I still want that last couple mph.

Any insights into this from anyone?

Just ordered the V4, I live in BC Canada so it looks like about a 2 week journey. Will be putting it on my 2021 Powerfly4. Just had a new motor installed when it failed after only having it 5 months. It started skipping, similar to a worn our socket or chain, shop even replaced 2 (smaller) cogs, charged me $45 and it still skipped. Turns out it was the motor, just picked it up and rode it home for 15KM worked great. Very excited to up the speed!! BTW, I didn't have a detuning device on it.

Hi, can anyone else share their experiences with V4? Anyone experiencing and dreaded errors yet?

Cheers

Have you tried using the forum Search function? Loads of info already there.

Yes, most of the feedback turned up relates to the v3 version. Can you link me to where feedback for v4 is discussed extensively?

Hi there,

Hi George,

Just as an update, I got my V4 from yourselves the other day via the Bay. All fitted up fine, was really worried that the available space was going to be a problem though, and at first was thinking 'hmm this motors gonna have to come out' with a view to poking the module up into the seat tube or summat (this is on a 2020 Haibike AllMtn3 btw).

The setup on my bike has a small black plastic cover screwed to the underside of the motor, then another much bigger piece of plastic (bashguard if you like) goes over that. The small cover sits pretty snug to the motor but with some careful jiggery pokery, head scratching and various attempts at layout I was able to get all the wiring, connectors and module inside (just!). Also a close call was removing the required screws that hold on both the plastic pieces - some of the bolts come VERY close to the chainring and again I first thought that I would have to pull the crank and then remove the ring but again I got lucky and was just about able to get the bolts out although I did need to reach for my ball headed allen keys, no way a regular key would have got in there.

All works as expected, really like the fact that everything still reads in MPH (including the V4 speed setting and range remaining). Battery percent is an awesome touch (I have a Purion) and is actually one of the big reasons I went for it.

My only gripe (which I have seen mentioned by others too) is that the V4 is set using the - button, long press 3 secs. I don't think this is ideal as the same button also controls the on screen display modes (long press 2 secs I think) so it's a bit of a pain not triggering the V4 on/off/speed setting when switching display modes. It can be done obvs, but you gotta be real quick letting off the button before the V4 triggers.

I would have thought it would make a lot more sense to control the V4 with the + button or maybe even the walk button. Perhaps theres software reasons why this isn't possible.

Anyway, I've made a note of my mileage, we'll see how it goes. Anything further I'll post it up here. Cheers.

I have Volspeed v4 on my 2022 Trek Rail 7 and just got a 503 error which won't clear and has baffled the mechanic. I have removed the volspeed v4 and had it reset but still no joy just constant 503 error. I'm awaiting a replacement speed sensor to test and hoping thats going to sort it!

Is the volspeed v4 detectable on the purion version of the Bosch gen4
My bike is new so has a warranty ...so can it be detected by the shop/manufacturer if things go tits up.
I only want to get to about 20mph as I seem to hit the limits of 15mph very early

Hi @jezza

No it's not detectable. A 20mph limit reduces the chance of getting an error to virtually zero. VOLspeed set the max speed to 28mph so you'd be well under this limit.

Hope this helps

 

[Bob88]

Volspeed V4 = Best money I ever spent. No hint of error set to 21.8mph (the sweet spot imo).

I beg to differ. I installed a V4 on my Focus jam² 2020 bosch cx4 unit. After about 300km of riding with a Max speed set to 35kph, it decided to not turn on one day after being charged.
The motor was taken to my LBS and immediately, Bosch said they could see it had been tuned. Provided a run down of how they could tell it was tuned and voided my warranty.
Suffice to say, the authorised dealer who sold me the V4 wasn't interested in helping me at all.

 

[Ark]

That's why most people don't use them until the warranty period has passed.
I doubt the V4 had anything to do with why your motor failed.
might not even be the motor, could just be the connections from the ecu/battery got moisture in them and need cleaning or the ECU thing on your bars died.
I know the LED one even has it's own battery because you can try to turn it on without the battery installed and the LEDS still flash

 

[Stu12a]

All connections were checked as recommended by bosch before the motor was pulled and sent. They were able to tell by the power draw of the motor that it had been modified. It was clear as day to them.
This myth that they are undetectable is misleading and a false claim.

 

[Stu12a]

A new purion display was also sent out the check prior to the motor being pulled out

 

[Zimmerframe]

Out of curiosity. After rides, did you let the bike power itself off or did you power off ?

Yep, always let it power down itself. But from memory, that wasn't a requirement or an instruction on the V4.
There wasn't any issue with error codes coming up. The bike simply didn't turn on one day and Bosch were quick to say its been tuned the moment they got the motor on their bench

 

[Peaky Rider]

Did they repair the motor for you, at a cost, or did you have to buy a new one?
I was thinking of fitting a Volspeed 4 to my Rail but you've made me think twice now.
