CAROL 2.0 Bike Discount Code
CAR.O.L Bike (Cardiovascular Optimization Logic bike) releases a special Black Friday discount code.
There is a Black Friday discount of £/$250 at CAROL Bikes with code TFK until Sunday 27 Nov 2022, after which, my TFK100 code will give you £/$100 off.
This is the biggest ever discount for Carol Bike 2.0.
CAROL bikes are an intriguing fitness concept. They are claimed to be high-spec, gym-quality bikes sold mostly to the home market (gyms too). Their USP is around the benefits of very short-duration, glycogen-depleting interval workouts which you can literally do without breaking into a sweat eg 2x 20 seconds @maximal. In and of themselves these workouts are claimed to boost VO2max, certainly for the non-athlete type of person.
CAROL doesn’t claim weight loss based on those specific workouts but that’s where you add in a once-weekly endurance workout.
As always there’s lots of science that underpin this. From what I’ve seen it doesn’t appear to be paid for by the manufacturer and, indeed, I vaguely recall seeing something on the BBC with Dr Michael Mosley a couple of years ago on this topic.
I guess the bottom line is that this probably will boost fitness (VO2max) in certain individuals but there are other physiological markers that are also important to athletes. That said, a quick win to boost VO2max for most people is probably a great idea.
Price: The bike starts at just over £/$2,000.00 plus a monthly subscription and prices are competitive with Peloton and Nordic equivalents.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
