Service or replace the bottom bracket in your Alpha 1

The first-generation Vvolt Alpha is equipped with a cadence-sensing, English-threaded square taper bottom bracket. Symptoms that require service include:<ul><li>Creaking while pedaling</li><li>Play when rocking the crank arms back and forth&#xA0;</li><li>No motor response, but walk mode functions&#xA0;</li></ul>The bottom bracket is wired, and the drive-side cup has notches.&#xA0;<img src="https://attachments.gorgias.help/q0jJY2DMD07eBWMO/hc/z8QbV2PYZe7ogePy/2025072320-f8e809c5-12e8-4a63-8ec5-5fe23d5e58c9-tempimageum4e0z.jpg" style="width: 600px;" class="fr-fic fr-dib fr-rounded">Ye Olde Cadence-Sensing Square Taper Bottom Bracket&#xA0;To avoid damaging or severing the wire during removal or installation, follow these handy instructions!&#xA0;This instructional document begins after the removal of the Alpha cranks, which requires an 8mm wrench to remove the crank fixing bolts and a square taper crank puller to remove the cranks.
