We chose this company based on the stellar Trip Advisor reviews! Wow, we did not have that experience at all. The guide was 5 stars, and we tipped him generously.
But the bikes themselves were UNSAFE. They were not in good condition as promised -- insufficient braking capability, loose steering, no night lights, inconsistent operating brake lights (important when following another bike in the dark), loose ebike control panels (flopping around on the handlebar).
Staff did not make any attempt to help you adjust the seat height for proper riding, check the brakes, or to ensure the lights worked (front and rear), or that the bike was in SAFE operating condition. There were six people in our group, and ALL of the bikes malfunctioned in some important way or another.
Reflective vests should be mandatory for a night tour, not optional. Weeks before the tour, we were assured by phone that the entire tour was on bike lanes and not on busy streets. WRONG. Poor brakes on busy streets with cars who can't see you + no front light = recipe for accident. We were just lucky. Don't believe their marketing hype.
