Collection: Hometrainer

An exercise bike has become an indispensable tool for cyclists and triathletes who want to stay in shape all year round. Whether it's raining, snowing or windy outside, a smart exercise bike allows you to continue your structured training indoors with the same intensity and precision as out on the roads. At Transition Zone, we have carefully selected three of the most popular and reliable models on the market: Wahoo Kickr Core, Tacx Flux S Smart and Wahoo Kickr Bike Shift Smartbike. These trainers are ideal for both serious riders and those who want to make indoor training more fun, more targeted and data-driven.

Indoor trainers have undergone a technological revolution in recent years. They are no longer just simple resistance devices – today they function as advanced training tools with built-in wattage measurement, automatic gradient simulations and integration with training platforms like Zwift, TrainerRoad and Rouvy. The result is a realistic and engaging training experience that brings the outdoors inside – and helps you become a stronger and more efficient cyclist.

The Wahoo Kickr Core is a direct-drive smart home trainer that combines reliable wattage measurement with impressively quiet operation and high compatibility. It's a popular choice for both beginners and advanced riders who want a serious training solution without paying a premium price. The Kickr Core measures your power output with an accuracy of +/- 2%, and can simulate inclines up to 16%, delivering up to 1800 watts of resistance – enough for even the most intense intervals.

One of the biggest advantages of the Wahoo Kickr Core is its compatibility with both ANT+ and Bluetooth, making it easy to connect to smartphones, bike computers and online training platforms. It is also known for its high stability and easy setup. With the Kickr Core, you get a home trainer that can be used all year round and elevates your training level without breaking the budget.

The Tacx Flux S Smart from Garmin is another strong mid-range offering. This direct-drive trainer is ideal for riders who want a solid and reliable setup for both structured training and interactive sessions on platforms like Zwift. It measures with an accuracy of +/- 3% and offers resistance up to 1500 watts – enough for the vast majority of users.

The Tacx Flux S Smart is known for its compact form factor and quiet operation, making it an obvious choice for riders training in apartments or rooms with limited space. At the same time, it offers a natural riding feel and robust build quality. It supports 8-, 9-, 10- and 11-speed cassettes and is easy to install. Tacx is also integrated with the Garmin ecosystem, so you can easily sync data across your devices.

If you're looking for the ultimate training experience, the Wahoo Kickr Bike Shift is close to the best on the market. It's a fully adjustable smart bike that combines Wahoo's precision and quality with the comfort and functionality usually only found on professional setups. You can adjust the saddle position, crank length, handlebars and gear settings, so you get an identical feel to your road or triathlon bike.

The Wahoo Kickr Bike Shift delivers an ultra-realistic riding experience with built-in gradient simulations, fast electronic resistance and stepless gear shifting. It measures with an accuracy of +/- 1% and is compatible with all popular apps. There’s no need to mount and dismount a rear wheel or chain – just jump on, turn on the power and you’re ready to train in seconds. It’s a game-changer for riders who take their training seriously and want maximum convenience.
