diagram showing critical Swift dimensions

The Swift frame is remarkable in that it accommodates a large range of uses for cyclists of almost any size and shape. Part of the reason for this is that the seat post has a great deal of vertical adjustment and is oriented at 72 degrees, which means that adjustments to the seat-to-pedal distance simultaneously change the horizontal reach of the bike as well.

This diagram illustrates the key dimensions and geometric relationships for the frame. The table below provides the specific values for seat-to-pedal distance and reach for various positions of the seat post. Note that the seat may be moved fore and aft by about +/- 1/2 in (12mm) from these nominal values by adjusting the position of the seat on the seat post.

Seat-to-pedal distanceReach with standard stem
30 in (750mm) 18.0 in
32 in (800mm) 18.5 in
34 in (850mm) 19.0 in
36 in (900mm) 19.6 in
38 in (950mm) 20.1 in



The standard stem on the Swift is 60mm, 40 degree, 1-1/8in threadless. Swapping a 100 mm 30 degree stem will increase all of these reach dimensions by about 1.5 inches (37.5mm). We configure the bike at the factory with a 100mm stem for riders taller than 5' 10" (1.8m) and a 60mm, 5 degree stem for riders under 5' 5" (1.65m). Most riders find that no vertical adjustment to the handlebars is necessary. However, there are two ways to adjust this dimension if desired. First, the stem can simply be flipped over, angling it slightly downward instead of upward. Second, the vertical stem riser can be easily shortened by cutting off a few millimeters from it's height.

image of Swift overlayed onto a Trek hybrid bike Some people have asked us how the Swift geometry compares to other bikes. The short answer is that it is very close to a "hybrid" geometry. The image to the left is an overlay of the Swift on the outline of a Trek hybrid bike. You can see that the wheelbase is essentially identical. The seat-to-handlebar distance is also nearly identical. This explains why the Swift has such a solid feel and comfortable ride.
