SpeedBox 3.0 chip for e-Bikes with Bosch Motors 2014-2025, tuning kit, speed unlimited

Works perfectly

So easy almost plug in and go.

Definety does as advertised. It is easy to install . Maybe slightly awkward fitting the chip back into the space on my bike

Only used a couple of times fitted to a Cube Bosch motor. Worked fine initially and was fantastic but then failed showing error and became unusable. Motor fine when Speedbox removed. Bosch cycle shop had also had the same problem but replacement worked fine.

Easy to install, took 2 mins if not less. Shoots me up to 30 mph plus in a matter of seconds. Love it

Much better bike to ride with this chip fitted. Completely changed my bike , superb.

Does not come with the crank puller as advertised. Yet to instal due to this. Hugely disappointing as I will have to pop to the LBS to get this thinking I had all my tools ready.

Too many cyclists with 4th generation [2020] Bosch motors using Speedbox2 have probably experienced the sudden loss of power as the motor enters limp mode [Error 504]. Speedbox3 is supposed to have solved this problem. I have to say, from my experience, it hasn't. According to Speedbox, as long as you let the e-bike display return to zero before turning it off, the Speedbox3 was supposed to somehow cleverly over-rideBosch's firmware that detected the presence of some external software and punish the cyclist with a shutdown of the motor. You then have to cycle for an hour or so without motor assistance to return to normal [but you could only do that twice before, on the third time, a complete shutdown requiring a Bosch engineer to fix it]. I was absolutely fastidious in only turning off the display when it had returned to zero. Alas, the motor has gone into limp mode and I am half way through cycling the bike with no motor assistance to hopefully get it back to normal. In the meantime, I have ordered a Badass Box which uses a completely different method of fooling the motor.

Eerst even getwijfeld of ik dit wel zou aanschaffen (*5min haha*). Maar na 2 dagen mijn nieuwe fiets gereden te hebben en iedere keer zodra ik boven de 25km.p.u. kom net of de rem erop ging toch maar besteld. En merk nu dat ik al snel rond de 30km.p.u. aan het touren ben. Uiteraard ook even geprobeerd om volle bak te gaan (*waar het kon*)en de 57km.p.u. aan getikt. Super blij mee. Het enige probleem was dat ik mijn crankbout er niet af kreeg. En dol draaide dus moest de boel eraf boren.

Produit facile à poser et efficace

Einfach anzubringen lässt diese Box die 25kmh-Bremse verschwinden. Bei einem schweren Mountainbike echt sein Geld wert

Ottimo prodotto, di facile montaggio e buon risultato

My Trek Verve +2 ebike is now unlocked. I now have assistance up to 50kmh; which is where I set the limit
