The BH Fitness RDX1.1 is a heavy indoor cycle for riders who want a studio feel at home. Its most unusual feature is the rear-mounted 20 kg flywheel, which BH says makes it the only bike in its indoor range with the wheel at the back. It suits riders who want a solid, road-style position and are comfortable with a friction brake.

In its favour
- A 20 kg rear-mounted flywheel, the only rear flywheel in BH's indoor bikes per the listing.
- Multi-position adjustment on both saddle and handlebars.
- A 130 kg max user weight on a 47 kg bike.
Good to know
- A friction brake needs pad checks over time, unlike the SB Mag's magnetic brake.
- The listing says little about the console or data shown.
Our take
The rear flywheel and brake
Most indoor cycles carry the flywheel at the front, under the handlebars. The RDX1.1 places its 20 kg wheel at the rear, and BH describes the result as new sensations during training. A 20 kg flywheel is heavy by home standards, which helps the pedals keep turning smoothly through the dead spots of each stroke.
Braking is by friction, with an intensity selector offering eight levels and what BH calls precise selection. Friction brakes give a firm, direct feel, but the pads wear over time and should be checked as part of normal upkeep.
Fit and adjustment
Both the saddle and the handlebars offer multi-position adjustment so you can set a position close to your road bike. The listing does not give the adjustment ranges in centimetres, and its height figures are inconsistent, so riders at either end of the height scale should confirm the fit with BH or the manual. The maximum user weight is 130 kg.
Weight, footprint and console
At 47 kg, this is a bike that stays where you put it. The listing does not give its full dimensions, so measure your space generously. Data is thin: the spec table mentions a speed monitor, but the bullets do not describe the console, and there is no mention of Bluetooth or app support.
RDX1.1 against the alternatives
The BH SB Mag shares the 20 kg flywheel mass but uses a quiet magnetic brake and is rated for heavy weekly use. The VirtuFit Stage 2.0i adds a 22 kg flywheel, 24 levels and Zwift and Kinomap support. The RDX1.1 stands out for its rear flywheel layout and direct friction feel rather than for features.
Verdict
Choose the BH RDX1.1 if you want a heavy, road-like indoor cycle with a firm friction brake and do not need apps or detailed data. If quiet running and low maintenance matter more, the BH SB Mag's magnetic brake is the better pick. For connected training with Zwift or Kinomap, go for the VirtuFit Stage 2.0i.
