Le Speedbox 3.0 est un excellent produit pour ceux qui souhaitent exploiter pleinement le potentiel de leur vélo électrique avec moteur Bosch. L’installation est simple si vous êtes un peu bricoleur, et les instructions fournies sont claires et précises. Une fois installé, la différence est flagrante : le vélo n’est plus limité à 25 km/h, ce qui rend les trajets beaucoup plus rapides et agréables, surtout sur de longues distances.J’ai apprécié la compatibilité avec les moteurs Bosch récents (2017-2024), ce qui prouve que le produit est bien conçu et adapté aux dernières technologies. Une fois activé, tout fonctionne parfaitement, et le moteur reste fluide et réactif.Côté sécurité, le système peut être désactivé facilement si nécessaire, ce qui est rassurant. Je recommande vivement à ceux qui roulent sur des routes privées ou qui cherchent à améliorer leur expérience de conduite.Un investissement que je ne regrette absolument pas !

Attempted to use on 2021 Trek Verve 2+ that uses a Bosch Gen 3 Active Line motor and discovered the speedbox 2-pin speedometer connector has different keying to the OEM one and makes it very easy to crush the pins within the connector. If damaged, those pins are not repairable and require a whole new $700 motor replacement. Do not recommend this product, if you want a faster E-Bike, buy a faster E-Bike.

Used with a Bosch eBike system 2 - Performance Line.Works as advertised, removed speed limit while keeping all other functions. Ability to turn on and off.I first tried the Volspeed V4. A comparison: Installation is very similar for the Volspeed V4 and the Speedbox 3. The Speedbox is slightly smaller/easier to fit. Speedbox on/off is slightly easier to activate. There is more, and better, instruction information for the Volspeed V4. But the Speedbox instruction diagram gets bonus points for showing my specific model.Overall the two are very similar. When I installed the Volspeed V4 the Intuvia display worked properly, but it would not actually activate the electric assist. I returned the unit. The Speedbox 3 worked on first install.The bit of extra speed is much safer in low speed traffic. Keep up with the cars rather than having them try to pass (especially on narrow roads) because they want to drive a few mph faster.I've also tried the "hack" of relocating the speed sensor to the pedal. That works in terms of functionality, but has poor reliability, poor weather resistance, doesn't give a proper speed. It's worth the upgrade.

Works better than advertised....I ride with top guys. I was getting gapped at 30 mph. Now I get assistance at 40 mph. Incredible tool to help older riders stay in the group. I love it.

This was easy to install, didn’t take long at all.It’s Easy to activate at the start of the ride, or during, and when it’s activated the power just keeps coming.Prior to installing this I found my eMTB reaching the 20mph assist limit when I was riding to and from the off road fun, and peddling along a 50lb machine at 22mph without assist was hard, now the assist keeps on coming, and I’m spinning out before the assist stops, so I’m not sure how fast it will assist up to, but I’ve spun out at 32mph.Love having the extra assist over 20mph!

I have a Tern HSD S+. Removed the side panel without removing the pedal. Pulled out two plugs and put this sucker inbetween. Everything is color coded and only fits one way. Overall install took 10 minutes with a star screw tip. I’m going 28-30 mph on flats now. This matches my natural cadence now. No more annoying cut off.
