Jamis Hudson 3

Jamis Hudson 3 - M


Jamis Bicycles has been featured previously for their popular Commuter series, which have a "fast hybrid" look. This bike is a little more relaxed, aimed at a recreational or around-town audience.

Similar to the Raleigh Circa or the Electra Townie, the Jamis Hudson 3 is a comfort or "hybrid" bike with an 7-speed internal gear hub, upright riding position and relaxed frame geometry, for about $600. Like the Raleigh bikes, it lacks fenders, but has fender and rear rack attachmetd points. It also appears to lack a kick-stand. However, the front chainring and chainguard are well designed and should keep your pants clean. The choice of straight handlebars on a comfort-oriented bike of this type is odd; Electra does the same thing with the Townie, and it feels strange there as well.  The quick-release wheels and seatpost clamps are fine for a recreational or rural rider, but a poor choice in the city. But, at this price, one could afford a few modifications. Fenders, LED lights, a change of handlebars, and a rear rack would still leave the price below $700 for a fully equipped bike for the rest of us.

Geometry


Unlike the Electra Townie, with its "crank-forward" design, the Hudson achieves a far-back, low seat the old-fashioned way, with a slack, 67 degree seat tube angle. This really is superior, since the bottom bracket is at the place where the tubes meet, providing greater strength and better looks, and the angle between the pedals and the seat is the same no matter how high your raise the seat. The shallow seat tube angle puts your legs farther forward in relation to your hips, allowing the gluteus muscles to be better used while sitting in an upright position, compared to a hybrid or comfort bike with a steep (say 74 degree) seat tube angle. It also makes it easy to put a foot down at a red light without leaving the saddle.

The Hudson is also available with a derailleur, and without a suspension fork, for $400, comparable to many hybrid or comfort bikes. This frame has a nicer sweep to it, due to the normal front fork, and front suspension doesn't do much on an upright bike like this, where most of the rider's weight will be over the rear tire. Jamis would do better to give the Hudson 3 a regular steel fork, while adding a suspension seatpost, or to go with wider tires, like the Schwalbe Big Apples or Fat Franks. But if you like its looks currently, it's a good buy.

Nice looking bike, but I agree with all of your criticisms.
