Flow Fitness Perform B3s exercise bike

The Flow Fitness Perform B3s exercise bike is a sturdy ergometer bike for anyone who wants to train seriously at home and, according to Flow Fitness, is built for heavier use such as in clinics and hotels. The quiet induction resistance with 48 levels, the TFT screen and a maximum user weight of 150 kg make it suitable for both cardio training and targeted intervals.

Thanks to its longer frame, the B3s is extra stable, even when you sprint out of the saddle.

Flow Fitness Perform B3s exercise bike at a glance

• Up to 150 kg user weight: a robust bike that stably supports heavier users too.
• Built for intensive use: suitable for daily training and, according to Flow Fitness, also for a clinic or studio.
• TFT screen with 16 programmes: 3 of which are heart rate controlled, for structured workouts.
• Bluetooth with Kinomap and Zwift: train with virtual routes and online challenges.
• Low step-through: easy to get on and off.
• Adjustable saddle and multi-grip handlebar: for users up to around 210 cm tall.

Stable and robust

The B3s has a footprint of 120 x 55.5 cm and weighs 44.2 kg. This extra weight and length keep the bike firmly in place, even at a high cadence or when several users train on it. With a maximum user weight of 150 kg, there is plenty of margin for intensive use.

Resistance and programmes

The induction resistance brakes the flywheel electronically, without friction. This keeps the bike quiet and low-maintenance. With 48 levels you can fine-tune the effort. The console shows time, distance, speed, calories, heart rate, RPM and wattage, so you can track your progress closely. Quick keys for resistance let you change quickly during intervals.

Training with heart rate and apps

You measure your heart rate with the hand sensors or a Bluetooth chest strap. The heart rate controlled programmes automatically adjust the resistance to your heart rate. Via Bluetooth you connect to Kinomap or Zwift for extra motivation.

Good to know

The B3s needs slightly more space than the more compact B2s. If you have little room and your weight stays below 140 kg, the B2s is an alternative.
