TAKING IT TO THE LIMIT
All our frames and forks are tested continually to meet or exceed (in some cases, well exceed) EN standards 14764, 14765, 14766 and 14781 as well as the new ISO 4210 standards. We conduct these tests at our frame manufacturing facilities, but we also use EN accredited testing laboratories such as Intertek and SGS to verify the results of our own tests. If these tests aren’t telling us everything we want to know about our bikes, we increase the loads and cycles, or we determine another way to test. Where current hydraulic testing machines, jigs and hardware aren’t up to the task of emulating some of the forces and impacts our bikes might be subject to, we’ve designed our own.
We relentlessly cycle test for fatigue from pedaling and torsional forces on every single frame size, with deflection tests for stiffness at every point of the frame. Brutal impact tests with massive weights dropped on fixed frames or forks are performed. Then reversed, with weights attached to the frame, the frame hoisted to a given height depending upon product type, then released.
This destructive testing is enormously instructive and important. And it is in continual process. But it’s our ongoing non-destructive testing of frames and forks fresh off the factory floor that’s just as vital.
For our carbon fiber frames, EVERY frame is weighed to make sure it’s neither resin rich nor resin deficient. We also measure the stiffness of each frame in 6 critical areas as a check on lay-up production. Each deflection test must fall within 5% of the standards our machine and field-testing have established. This weighing and stiffness deflection testing guarantees every single frame we produce meets all Jamis manufacturing protocol and will
deliver the ride qualities we defined and demand.
TOP FIVE THINGS YOU NEED TO KNOW
Lady Bug’s mini-moto “Y” frame design offers plenty of stand-over clearance for the youngest of new cyclists.
We offer real ball bearing (not plastic bushing) wheels with 16 spokes that will roll smooth and last long. Same thing for the crank and headset on Lady Bug: both offer full ball bearing construction so the ‘lil Lady can pedal and turn comfortably and securely.
Those wide 2.125” tires offer a large contact patch for stability and control, and they’re pneumatic rubber, not rock solid plastic, so they can be filled with just the right amount of air to provide a comfortable ride.
Our full-length & full chainring-wrap chainguard keep clothes & legs cleanly and safely out of the way of the chain. while our fenders not only keep puddle spray off the bike AND the rider, they also help to keep feet and hands away from spinning wheels.
If a steel or alloy part is not painted or anodized, we protect it with a black electro-plating which enhances the corrosion resistance of that part. Black may not be the most traditional or obvious parts color choice for a girl’s bike, but the black electro-plating finish won’t scratch & flake as easily as pink or white paint will.
