I drove all the way from Seattle to bring my daughter's scooter to ProMechBC and I could not be more pleased with both the repairs and the customer service. I will definitely be bringing the scooter North of the border when it needs some love.

Recently had an accident with my Apollo Go — luckily nothing major was damaged, but it still needed some repair and replacement parts. Service was great, and I got my scooter back within a week. :D

The service was incredibly fast, professional and efficient — they fixed my scooter wheel quickly and the quality of the repair was outstanding. Honest, reliable, professional and fast.
