What Display Can I Use With My Yamaha PW Series ST Motor, That Can Connect To My Phone Via Blutooth And Apps

For a Yamaha PW Series ST motor, the display you want is the one that gives you Bluetooth and app connectivity rather than the basic LCD many ST-equipped bikes shipped with.

Yamaha's app-capable kit for the PW family is the Interface X (the small top-tube button/controller) paired with a Bluetooth-enabled head unit, and the wider "Y" display ecosystem that talks to the Yamaha companion app. That's the route to phone connectivity - the older Display A / LCD units don't do Bluetooth at all, which is exactly the limitation you ran into.

The honest catch: which Y-series display and switch combination will actually talk to your specific ST motor depends on the motor's firmware generation and the wiring connectors on your bike. ST is an older-generation unit, and Yamaha's newer Bluetooth displays were designed around the PW-X3/CE-era systems. So before you buy anything, the thing that matters is whether your ST's harness and firmware are recognised by the display you're eyeing - that's where these swaps usually fall down, not the physical mount.

A couple of things I genuinely can't confirm from here and don't want to guess at: • The exact Bluetooth display model number that's verified compatible with the PW-ST specifically

• Whether your bike's loom uses the connector the newer display expects What would let me give you a straight yes/no:

• The model printed on your current display and side switch • The motor firmware version if you can read it

• Ideally a photo of the display connector If you can dig those out, I can point you at the right unit rather than sending you down a £200 cul-de-sac. Worth checking Yamaha's own compatibility chart for your motor generation too - that's the only document that settles it definitively.

One side note: your profile lists the bike as a Haibike AllTrail 5, and I've had a couple of conflicting notes on what motor that actually runs. If you can confirm the ST is what's physically in your frame, that keeps us honest - the display question hinges entirely on the motor generation being right.

Good - now there's something concrete to give you. Here's where things actually land: Your two genuine options for Bluetooth/app connectivity on the PW-ST are the Yamaha Display C and the Interface X.

Yamaha Display C It has Bluetooth built in, pairs with your smartphone, and supports apps including Komoot for turn-by-turn navigation. It's a 2.8-inch colour screen showing speed, battery, support level and clock.

On PW-ST compatibility - a Haibike Trekking 6 is known to use both the PW-ST motor and the Display C together, which is about as close to a real-world confirmation as you'll get without Yamaha spelling it out explicitly.

Several online retailers list the Display C as compatible with all Yamaha units from 2019 forward, though Yamaha's own site says 2022 forward - worth checking with your dealer on that distinction.

Yamaha Interface X It connects to smartphone apps via Bluetooth and can also be expanded with third-party bike computers from Garmin, Sigma or Echowell. It's the more minimalist of the two - small top-tube button/controller rather than a full display screen.

There are reports of the Display A being swapped for the Interface X on PW-ST bikes using the same connector, which bodes well for fitment.

The connector question Yamaha's own drive system manual covers Display A, Display C, and Interface X together for the PW-TE, PW-CE, PW-ST, PW-X2 and PW-X3 - so Yamaha themselves treat all three displays as part of the same ecosystem for your motor. That's probably the strongest compatibility signal you'll find short of fitting one.

Bottom line: Display C is the one to go for if you want a proper screen + Bluetooth + phone app. Interface X if you want minimal clutter and are happy using your phone/head unit as the display. Both should be connector-compatible with your PW-ST - but double-check the year caveat on the Display C before ordering, and if in doubt, ask the seller to confirm against your motor's year.
