IN-HOUSE EXPERTISE

Hub motors, mid-drives & batteries

LAWTON, OK

Serving SW Oklahoma & Fort Sill

Welcome to E-GRIN BICYCLES

Lawton’s dedicated home-based e-bike repair & custom conversion service. You don’t need an expensive retail showroom to get pro-grade mechanics. Operating from my home workshop, I keep overhead low so the savings go directly to you.

Expert E-Bike Services From My Home Workshop

From SW Oklahoma to the Wichita Mountains, I handle complex diagnostics, assemblies, and custom builds with personalized, one-on-one attention. Most traditional bike shops won’t touch hub motors, mid-drives, or custom lithium batteries — I do.

Custom E-Bike Conversions

Convert any traditional bicycle you already own into a high-powered electric ride for a flat fee. Bring your bike and your kit, or let me recommend the exact parts you need to order.

Stripped gears or electrical faults? I diagnose, repair, and program smart controllers (hub motors and mid-drives) to get your power back to 100%.

Routine Maintenance & Box Assembly

Heavy e-bikes wear components quickly. Bring your bike for hydraulic brake bleeds, tire/tube swaps, or adjustments. Just ordered a Lectric, Aventon, or Rad online? I’ll professionally unbox and assemble it so it’s ready to ride.
