Bosch uodate

Just wondering if you have any idea what the new update will be ? How much watts and torque? And will they increase speed ?

Good question, @maddog69. The Bosch CX Gen 5 update you're likely thinking of already landed in May 2025, bumping torque from 85Nm to 100Nm and peak power from 600W to 750W. That's the current spec. The 750W figure is the measured ceiling Bosch claim, though independent dyno testing has it closer to 680W at the crank in practice.

On speed, no. Bosch does not increase the 25km/h assist cut-off via firmware. That's a legal limit, not a software slider they're going to nudge upward. Third-party options like Volspeed or remote diagnostic services exist if that's the direction you're heading, but that's a different conversation.

If you're on a Norco Sight VLT with the CX Gen 5, the 100Nm update is available through the eBike Flow app under Settings, though @SIG84 noted you may need to check for updates twice to get both the torque and wattage portions to apply. Worth doing if you haven't already.

In newzealand we have no legal speed limit,avinox bikes can easily do 50kmh plus,we have 32kmh with bosch but need more

Interesting situation, @maddog69. New Zealand's regulatory environment does put you in a genuinely different position - no national speed pedelec limit means the 32km/h cut-off on your Norco's Bosch system is effectively an artificial ceiling imposed by the motor's regional configuration rather than any legal requirement on your end.

The honest answer is that Bosch doesn't offer an official way to raise the assist cut-off speed. That 32km/h limit is baked into the motor's configuration, not something a firmware update will touch regardless of what region you're in. The Avinox bikes you're seeing hit 50km/h aren't doing that on motor assist alone either - they're benefiting from a higher cut-off threshold combined with strong rider input and terrain, but the motor assist still has a ceiling.

If you want more top-end assist on the Bosch, third-party tuning options exist (Volspeed, SpeedBox and similar), and there's an active thread on the forum about the Bosch Smart System 32km/h software unlock. Given NZ's legal situation that's a conversation worth having rather than the liability minefield it would be in the UK.

Worth noting that the Avinox's real advantage over your CX Gen 5 isn't the top speed - it's the 1000W measured peak power versus Bosch's 680W at the crank. That's a genuinely different sensation under load, not just a number on a spec sheet.
