Indoor Bike Trainers


Function
The function of indoor bike trainer is to allow cyclists to ride their bikes indoors. A bike trainer essentially turns the bike into a customized stationary cycle. During winter months, many cyclists use the trainer to continue their level of fitness and build muscle. Trainers allow cycling in a very controlled environment, with no weather elements to effect performance. After injuries, cyclists use bike trainers to get adjusted to riding again.
Types
There are many types of bike trainers. Magnetic bike trainers, fan trainers and fluid trainers lock the back wheel in with a clamp. They have a roller positioned below the back tire to create resistance. Magnetic trainers create resistance for the rider by a roller powered magnetic flywheel. Fan trainers create resistance by using roller powered air fans. Fluid trainers use resistance created by the magnetic flywheel and fluid chambers combined. Roller trainers are sets of rollers that allow freedom of movement while riding. These trainers don’t lock the back wheel in, so the bike is free to move back and forth along the rollers.
Features
All bike trainers allow for indoor cycling. Fan trainers are a low-cost bike trainers. Fan trainers are the loudest of the trainers, and have limited resistance. Magnetic trainers are quiet trainers that have a higher level of resistance than fan trainers. Fluid trainers are the quietest of all the trainers, and the most expensive. They offer resistance beyond both magnetic and fan-powered trainers.
Benefits
There are many benefits of using indoor bike trainers. In dangerous weather conditions, the trainer allows cyclists to continue riding their bikes without the risks that exist outside. Bike trainers allow less confident riders to get comfortable with their bike before taking it outdoors on the roads. Injured riders use trainers to get back into riding without overdoing it; they can quit whenever they become fatigued.
Potential
The future of trainers is bright. New computer software simulates outdoor bike rides, customizing the speed to that of the rider. DVD’s by top bike trainers offer indoor riders great workouts. Eventually, indoor cycling will be high-tech virtual cycling that displays graphics on a computer screen and adjusts the trainer to the cyclists environment, allowing the rider to feel like they’re outdoors.
Warning
Even though bike trainers hold the bicycle in place securely, it is still possible to tip it over. Be aware that the bike trainer will not completely ensure that the bike stays upright. Other potential problems are specific to the type of trainer. Magnetic trainers are prone to breakage when used heavily. This is also true of fluid trainers. Due to overheating, they sometimes spring leaks from their fluid chambers when used for long periods.
