I'm posting this from the Highway 17 Express bus going home. My Specialized Roubaix 30 speed carbon fiber road bike is sitting at the front of the bus in the bike rack. As we zoomed along I-280 in San Jose at abou 60 mph THE BIKE RACK BROKE, leaving my bike dangling inches from the pavement at the front of the bus!
The bus driver pulled over and moved my bike to another spot on the rack. Disaster averted.
Apparently, those Sportworks 3-space "Trilogy" bike rackscan break while in use! King County removed all of their Trilogy racks because of problems with the 3-space racks they experienced in the Seattle area that Sportworks claimed was user error -- cyclists were not properly securing their bicycles.
Santa Cruz Metro uses the 3 bike racks on all of their buses, but I haven't heard of problems until my experience tonight.
IMPORTANT: Please post comments for this article at the new CYCLELICIOUS 2.0 version of this page.
If I'm not wrong about the design, the only real support that keeps the bikes from moving laterally due to the motion of the bus is the spring loaded support arms that go over the tire, correct? You mentioned the bus moving at 60mph but nothing about sudden brakes. Why don't they have a latch system that can be tightened around the rims, like they do for those Saris bike racks? Is it too time consuming to put them on, I don't think so.
Its interesting that it would break regardless, as Sportworks claim so much about safety during movement and what not. Atleast your bike didn't fall off.
I should clarify -- the spring loaded retainer arm broke completely off, leaving the bike flopping loosely in the rack. I was concerned because I heard a crack/crunch, looked forward and didn't see my bike. The bike bounced partially out of the track and was laying on its side.
The retaining arm puts pressure on the front tire to keep the bike firmly in place.
Carbon road bike on a bus rack! So there are people who do that... I was wondering if the owners of such sweet gear would be able to take the stress of it. Apparently so! I like the bike racks on London Ontario buses. They use a different method of trapping the wheel, with no springy arm involved.
I had a very interesting recommendation while taking the MST-25 (I think) express from Monterey to San Jose.
The driver told me to actually pull the spring arm all the way up until it clamped down on my front fork instead of my front tire. After observing the bike throughout the trip I have to say it looked a lot more stable. I would probably use that method again.
Both of my bikes are around $1200 retail and I use them on bus racks all the time. I can't say that I've seen any other higher quality bikes on the bus around here. I'd be a bit worried with putting a real $5k racing bike on one of those racks though.
One bit of advice: Taking as much weight of the bike as possible is best on those racks. With my commuter/cyclocross bike, I always take any bags/gear off the racks so there's less mass to be flopping around.
