Claud Butler Wrath 2.0 Cues — de-restrict by swapping controller or display?

I'm on a claud butler wrath 2.0 cues.

de restrict via changing controller/display.

The Claud Butler Wrath 2.0 isn't actually an eMTB, Ryan — it's a regular analogue hardtail with a Shimano CUES groupset and no motor. So there's nothing to derestrict: no speed sensor, no controller, no display, no 25 km/h cutoff. Your speed limit is your legs and gravity, and those are happily unregulated by EU law.

If you've genuinely got the non-assisted Wrath 2.0, then "controller/display" derestriction simply doesn't apply — there's no firmware in the way. The only way to go faster is the traditional one: more watts through the pedals.

A couple of possibilities worth sorting out:

• If you meant a different bike — perhaps an eMTB you also own — tell me the make, model and motor (Bosch, Shimano, Bafang, DJI etc.) and I'll give you the exact derestriction route, because the method varies massively between them.

• If you've fitted (or are planning) an aftermarket conversion kit to the Wrath — a Bafang mid-drive or similar — then yes, that changes things. On Bafang systems the speed limit is stored in the motor itself, not the controller or display, so swapping the display alone won't lift the cap. You'd reprogram it with a Bafang programming cable and software (or a tool like a Badass Box that spoofs the speed sensor without touching the motor firmware).

For reference, the general principle riders here keep coming back to: changing a display usually does nothing to actual support speed. As @Backflip has pointed out repeatedly with Shimano systems, the display speed adjustment only alters the readout on screen — the motor still cuts assistance based on real wheel speed, not what the screen shows.

So the short version:

If the Wrath 2.0 is the stock CUES hardtail — there's nothing to derestrict, and you're already "unlimited." If there's a motor involved that I'm not seeing, give me the system name and I'll walk you through the actual method.

Tell me which it is — stock bike, conversion kit, or a separate eMTB — and I'll get you a precise answer.

There indeed seems to be a Claud Butler Wrath 2.0 eMTB which is driven by a Bafang drive unit, see e.g. here.
However, due to the fact that I only know the "Shimano universe" and don´t have any clue in other systems, I am not able to add some knowledge related to this Bafang based bike.

Fair cop, @Backflip - and cheers for the correction. You're right, and I was wrong. There is indeed a Claud Butler Wrath 2.0 eMTB - the ebikes.co.uk listing confirms it's a Bafang rear hub motor setup with five assist levels and a handlebar display.

So to circle back to @ryan0x0's actual question: on a Bafang hub motor system, the speed limit lives in the motor controller, not the display. Swapping the display alone won't lift the 25 km/h cap - the motor will still cut assistance at the programmed speed regardless of what the screen shows.

The practical options on a Bafang hub system are: • Reprogram the controller - via a Bafang programming cable and the Bafang configuration software, you can raise or remove the speed limit in the controller settings directly.

• Speed sensor spoof - a magnet-based trick that makes the motor "think" the wheel is moving slower than it is, so assistance continues beyond 25 km/h. Simple and reversible, though it does affect your speed readout accuracy.

• Badass Box or similar - a plug-and-play dongle that does the sensor spoofing without touching the firmware. Popular for hub motor setups because it's bolt-on and easily removed.

Worth noting: the specific controller location and programming interface can vary between Bafang hub motor variants, so it's worth confirming the exact motor model on the Wrath before buying any cable or kit.
