euh okay ... :censored:

Are you sure, you have speedbox 3.0 with CX performance next gen ?

I do not know about the Volspeed. Might work just as good. Let us know.

no speed and odo work fine.

most recent update. Two friends also have speedbox 3 for Bosch 4gen cx. No problems.

I have 1.000 miles and no problem whatsoever. No limp mode. only 200% more fun.

Is that hearsay or a fact ?

Emtbehave, yes, the speedbox is illegal on public roads. I think we all agree. (Problem with a forum-formula is that every answer is connected to a prior remark or question.)

Graham, I can assure you, I am a decent respectable citizen :). Don't worry, never owned a gun. No plans in this direction. Don't like guns. Hope you needed a gun for your profession... But maybe the comparison with combat pistols is a slippery slope. I am sure you agree. So, 55 km/h is the...

Graham, 55 km/h is the maxspeed I've reached during a few seconds. (boys and their toys). Thanks for the motorcycle tip, but I already own one :). As I said, on trails, max speed of 25 is perfect.

Focus Jam2 6.8 Nine : Highest gear : 34/10. With 29 inch wheels the bike goes 7.87 meters with one complete rotation. One rotation/second gives me 60 x 60 x 7.87 meters = 28,33 km/h two rotations/second ==> +/- 56 km/h. The transmission efficiency in turbo mode = +/- 340% rider + bicycle weight...

Every modification to yourbike is an argument for invalidation of waranties. The speedbox is certainly no exception. So if the motor is dead, with the speedbox attached, I wont get a new one. Dead without speedbox (removable) : not sure if it is so obvious. Of course, your KIOX display...

update : after 400 km's with speedbox. No issues at all. perfect. it's amazing how fast you get used to the higher velocity.

I installed it a few days ago. If I start up : everything normal. restricted as before, but when I push the magic button ... I fly straight to the moon. Speedbox made the 3.0 to bypass the new software. They claim to have tested it for many many miles. No error. So, all I can say : I have been...

yes, so they say.

I have plugged the speedbox into my jam2. (Bosch cx performance) OMG ! Double fun. Inbetween trails, easily 35 km/h. With effort, speed up to 55 km/h, which is too fast.... I know... (had to try), Off Road, no difference, but on flat area, speed up to 28 km/h depending on the gear. On the...
