Penzance Workshop Service

BRING IT IN,
RIDE IT OUT

In or around Penzance? Drop your bike to us and we'll fit your conversion kit for you — plus carry out a range of modifications and upgrades to get your build running just right. Arrange a date through our contact page and we'll confirm where to bring it.

Professional fitting — we install your motor, battery and wiring so it's done properly first time, with labour quoted per job.

Modifications & upgrades optional — completely optional extras if you want them: tuning, accessory fitting and build improvements tailored to how you ride. Just need the kit fitted? That's all you pay for.

Drop-off in Penzance — bring your bike to us and collect it ready to ride. We'll share the exact spot once your slot is booked.

Can't make it to Penzance? No problem — all kits ship UK-wide with full install guides, and we're always on hand for support.
