New bikes and better-fitting parts

Bicycle assembly and component upgrades.

Professional installation, compatibility checking and a complete safety inspection before the bicycle is ridden.

All bicycle services

“Mostly assembled” is not fully checked.

A bicycle shipped in a box may still require careful adjustment, correct torque, wheel and brake checks, drivetrain setup and inspection for shipping damage. Professional assembly provides a known starting point.

Customer-provided components

John installs customer-provided parts in most cases after confirming compatibility and suitability for the bicycle. He reserves the right to decline an installation when a part is incompatible, damaged or unsuitable for a safe repair.

If you’re still choosing a part, John can help confirm compatibility before you order. Bring or send the bicycle make, model, year and the exact part information when possible.

Before you order parts or bring a boxed bicycle

Share the bicycle make, model and year, plus the exact component you want installed. Standards for brakes, wheels, drivetrains and mounting points vary, so checking compatibility first can prevent an unsuitable purchase.

For a boxed bicycle, bring the supplied parts and instructions with it. John checks assembly, adjustments and safe operation before it leaves the shop. Customer-provided parts are installed in most cases, subject to compatibility, condition and suitability for a safe installation.

Will you assemble a bicycle bought online?

Yes, in most cases. Share the make and model so John can confirm the assembly requirements.

Will you install parts purchased elsewhere?

Yes, in most cases, when the parts are compatible and appropriate for the bicycle. John will confirm fit before installation.
