This is the best place to send your trifolds for maintenance, and upgrades for their honesty, fair prices and ethics.
The trifold I owned wasn't purchased from them, but needed substantial repairs from an accident. Irregardless, they took the bicycle in for full maintenance for $180 (comparable prices with other trifold shops) with some requested upgrades.
Throughout the one week repair process, the mechanic called in to request consent for various findings and replacements.
Once repaired, the bicycle was in a much better condition when I purchased it with scratch marks covered by matching paint. I was prepared to pay the high premium for such a service.
So imagine my pleasant surprise when it only costs $50 for crucial component replacements such as wheel skewers, new brake lines, rear bumper lock.
The component costs were similar to stock prices (possibly cheaper than if you were to buy online individually) and were itemised fairly.
Thank you Bike Republic for the thorough servicing.
