Road & endurance
Efficient on tarmac; common subtypes include endurance, sportive, climbing and time trial.
Check:Look for gearing, tyre clearance, fit and luggage needs rather than the label alone.
Bike Index reference taxonomy
Choose a bike for the trip
Start with the route and riding style, then choose the bike. Category names are a useful vocabulary, not proof of fit or compatibility.
Gravel & all-road
A broad family spanning mixed-surface day rides, cyclocross and bikepacking.
Check:Surface roughness, tyre volume, mounting points and braking matter more than marketing categories.
Mountain biking
Trail, cross-country, enduro, downhill and freeride place very different demands on a bike.
Check:Match terrain, suspension travel, wheels, protection and maintenance access to the actual route.
Touring & bikepacking
Multi-day riding can use road, gravel, mountain or e-assisted platforms.
Check:Check loaded weight, luggage mounts, repairability, range and transport rules.
E-bike & adaptive cycles
Pedal-assist bikes, tandems, recumbents, tricycles and hand cycles expand trip options.
Check:Confirm legal class, charging, battery transport, access barriers and route gradients.

Frame labels, wheel sizes and component categories are not enough to confirm fit or compatibility. Use the manufacturer's exact specification and a competent bike shop for safety-critical decisions.
