Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 1999 Jamis Boss Cruiser and 2009 Jamis Boss Cruiser.
- Gearing
1999 Jamis Boss Cruiser has a 14% lower climbing ratio than 2009 Jamis Boss Cruiser.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
1999 Jamis Boss Cruiser had an original MSRP $155 lower than 2009 Jamis Boss Cruiser.
Original MSRP is the published list price when new, not today’s used-bike value.

Ratio2.44:1
Estimated speed at 90 RPMGear
Uses front tire 26×2.125; rear size isn’t listed.
How it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
