Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Handling
1998 Breezer Thunder has a 0.5° slacker head-tube angle than 1997 Breezer Thunder in the archived geometry. Frame size is not identified for 1998 Breezer Thunder and 1997 Breezer Thunder.
Fork offset, tire size and wheelbase also affect steering; head angle alone is not a handling verdict.
- Identity & price
1998 Breezer Thunder had an original MSRP $205 lower than 1997 Breezer Thunder.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.

RPM = pedal turns per minute.

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.

Historical specifications are presented as an archival reference. Components may have varied by market, size, or production run. Legacy reference geometry is model-level historical data whose corresponding frame size is not identified; compare those dimensions as reference values rather than size-normalized fit data.
