REP Fitness Strive Air Bike
An air bike whose fan blade angle adjusts mechanically — resistance you set, not resistance dictated by how fast you pedal.

Choose this one if
- You want to set resistance rather than have your cadence set it
- You want a console that talks to training apps over FTMS
- Two people of different heights will share the bike
The detail
Every other air bike here has one resistance curve, and it is fixed by physics: pedal faster, the fan meets more air, resistance rises with the square of speed. That is why an air bike is brutal at high output and nearly frictionless at low. The Strive's Variable Pitch Resistance changes the angle of the fan blades, which moves the whole curve rather than your position on it.
The practical consequence is that you can do steady low-intensity work without spinning your legs at a useless cadence, and you can do strength-biased efforts — hard, slow pushes — that a fixed-pitch bike simply cannot produce. REP describes levels 1 to 3 as easy cardio, 4 to 6 as the classic fan-bike feel, and 7 to 8 as harder than a normal air bike goes.
It is mechanical, not motorised, which is the right engineering. Resistance changes are immediate, there is nothing to plug in, and there is no electronics failure mode.
The console covers the metrics that matter — time, distance, calories, RPM, speed, watts — and watts is the one that lets you compare sessions honestly. It supports ANT+ heart rate straps and is FTMS-compatible over Bluetooth, so most training apps will read it. It does not talk to Apple Health directly.
Seat adjustment is height plus fore/aft, which is what lets riders of genuinely different sizes share it — REP quotes roughly 4'11" to 6'7". The handlebars do not adjust, though there are multiple grips.
The pedals are standard 9/16-inch thread and the seat post takes a standard bike seat, so both are replaceable with off-the-shelf parts. That is more than most manufacturers allow.
Compare the fixed-pitch alternatives: the Assault AirBike Pro X with its 27-inch fan and seven-year frame, and the belt-driven Fringe Raptor.
