CompuTrainer provides the most realistic indoor biking experience available. Whatever your starting point, you’ll improve significantly. Time-tested for over 25 years and backed by the only Performance Improvement Guarantee in the industry, it is proven to increase your cycling power by 20% and your speed by 2 to 4 MPH – or your money back!

CompuTrainer set the industry standard for repeatability (± 1%), accuracy (± 2.5%), power (1500 watts), quality, and service lifetime (10+ years). Exclusive performance features like Electronic Inertia for true road feel, SpinScan™ electronic pedal stroke analysis, and Adjustable Aerodynamic Drag Factor are all unique to RacerMate products, including CompuTrainer. Cycling and triathlon coaches worldwide use CompuTrainer as their primary testing instrument. Both USA Triathlon and USA Cycling test and train their team athletes with CompuTrainer. Most world champions, as shown in our athlete carousel at the top of this site, swear by it. You will too.

Important technical innovations that have significantly increased CompuTrainer’s training value: 1. SpinScan Pedal Stroke Analyzer, a key tool with all RacerMate products, will allow users to see how well they were applying torque to the pedals, but without the need to install expensive strain gauges on the bike. Showing left and right power and a 24-bar or 360 degree polar graph of torque, cyclists have instant feedback to improve pedaling efficiency.
2. Aerodynamic Drag Factor in the RacerMate software wind-load algorithm is individually adjustable. This industry first allows the rider to adjust the drag factor to account for their own body geometry and riding position. With this feature real-world accuracy increases another notch.
3. 2007 marked the introduction of a landmark improvement in the CompuTrainer interactive training experience: Interactive Real Course Videos.
These videos of famous triathlon and bike courses are filmed in High Definition and are then combined with our interactive, GPS mapped software to make you feel like you’re on the real course. Filming for most are on race day and provide superior realism and race simulation.
4. In 2012 RacerMate introduced RacerMate One. This added many new features to the software package, but the leading improvement was the introduction of SmartPacers™. These pacers allow the user to setup up to 7 opponents with varying difficulty levels, which when used this way allow the cyclist to do interval training without needing to do it in a fixed-wattage training. Wind-load (the same load curve applied to you on the road) could now be used for watt-based training!

Hardware and Electronics

Every version of CompuTrainer is built upon the same basic system of hardware and electronics. CompuTrainer also operates as a stand-alone electronic bicycle ergometer (no external software required) or pair two or more of them together using MultiRider or the RacerMate One’s 3D Cycling Application and get a team ride experience.

The CompuTrainer system that you own today will be with you tomorrow. We strive to make it easy to upgrade or add any new cutting edge software RacerMate develops in the future.

Software Features – RacerMate One


RacerMate One is our newest software platform and eventually all legacy software (with the exception of perhaps Velotron Wingate) will find its way to be part of it. After almost 20 years of software development and individual applications it became apparent the need to consolidate every RacerMate application into one package. Enter… RacerMate One.

Below are the key software elements of RacerMate One, but you can learn more about it on our Software Overview page.


Interactive 3D Cycling

What makes our 3D interactive graphics different? Curves, split screens, and panoramic helicopter views combine with advanced computer algorithms to create a true “road feel”. Select any course and apply scenes from a variety of scenery packs; like, Seattle (our home town) and the graphics are generated on-the-fly. This unique feature is what allows us to keep our courses free! You’ll get real-time data such as wattage, heart rate, speed, both real-time, average & peak values are given. Utilize racing your previous performances or use SmartPacers™ to hyper-accelerate your training.


Gain Power and Efficiency with SpinScan™ Pedal Stroke Analyzer

SpinScan™ is an exclusive feature designed to help increase power and efficiency. The graph represents torque output on a full 360 revolution. The right/left power splits give you the feedback needed to pedal in “circles”. It will identify “flat” or “dead” spots in the pedal stoke where optimal power is not transferred to the drive train. Dynamic bike fits utilizing SpinScan are an excellent way to take the subjectivity and guesswork out of the bike fit process. Use ATA (Average Torque Angle) to adjust your fore/aft position for optimum power.


Train with power using fixed wattage workouts – and more!

Power Training is the go-to app for fixed wattage workouts. Power Training will also run all other course types not available to other applications. Power Training is also the theater to playback previous performances; just load them up and hover your mouse over the data to get a precise readout of what you did and when you did it.


Interactive Real Course Video

Train on complete bike courses filmed on race day. Here is a terrific way to experience some of the world’s great bike courses without leaving your home. You’ll know the courses as well as the local athletes!



Unlimited Pre-Loaded Courses—Custom and Downloadable

Loaded into RacerMate One, which comes with every CompuTrainer, are hundreds of courses you can choose from. Click on the header over the course selector to sort them by distance or climbing elevation. Use the profile tools to view the course information or even loop a course, reverse a course, do a section of a course, or do an out-and-back on it. Truly unlimited! You can also use GPS data and GPS course tools available to ride courses you may have to prepare for. We upload courses often to our website, so look often to see if we’ve added new courses – which are always free!

Bottom Line – You Get Professional Performance

Looks can be deceiving. CompuTrainer is not your average bike trainer, though to many that is exactly how it appears. It is a very precise cycling ergometer able to measure your wattage, heart rate, cadence, pedaling efficiency, replicate real-world course – and matches the accuracy of laboratory ergometers costing up to 10-times more. For the individual user it is like having your very own exercise physiology lab at home. It is more powerful than other electronic bike trainers (except the Velotron, made also by RacerMate). CompuTrainer has a peak power rating in excess of 1500 watts to simulate road grades up to 15%. More durable than other bike trainers, the training stand is guaranteed – for life – against manufacture defects. You’ll enjoy the feel, the accuracy, and the longevity from owning CompuTrainer.

Velotron, like CompuTrainer, is a computer controlled, precision electronic bicycle ergometer/trainer, but of a proprietary new design. It provides the highest degree of laboratory accuracy and repeatability; the widest load range of any commercially available electronic ergometer; high durability/low maintenance; and an authentic road feel that closely simulates riding outdoors.

Using an innovative, patented, eddy current brake built around a heavy (55lb) flywheel it uses a fixed ratio high efficiency chain drive with internal freewheel to allow shifting “virtual gears” electronically. Velotron’s ultra-low starting effort of only 5 Watts is advantageous for rehab, cardio, pulmonary and orthopaedic applications.

Velotron is used worldwide by universities, sports science labs, and coaching/testing centers – often in conjunction with the optional Wingate software. Because of its superior accuracy, Velotron is the only bicycle ergometer ever approved for use in the USA Cycling National Talent Search. It is also the favored home cycling ergometer for those who want only the best money can buy.

A favorite for home users, use this model with your own bike frame and components

Top of the line fully adjustable ‘Dynafit’ frame

“Easy On/Easy Off” step-through frame suited for medical and rehab applications

Use Applications Personal Ergometer – Sports Science – Health Clubs – Medical Rehabilitation
Modes of operation Ergometer mode functions as a fixed wattage machine to adjust torque relative to speed to maintain a watt-constant. Gearing is non-adjustable in this mode and is fixed at 52/14.
Bicycle Simulation mode includes the effects of wind resistance, rider weight, rider aerodynamic drag factor, road grade, speed, acceleration and inertia. Gearing can be set to mimic the cyclist’s road bike in this mode.
Add optional Wingate software and you have a Wingate device that will allow multiple tests to run simultaneously without the heat-induced issues of other ergometers. Gearing is non-adjustable in this mode and is fixed at 52/14.



Accuracy, Repeatability and Load Range

Velotron creates loads from 5 to 2000 watts which covers the entire range of human capability. Accuracy is +/- 1.5% of reading across the entire load range. Repeatability of +/- 0.2 % or better. This level of accuracy/repeatability meets or exceeds that of competitive laboratory bicycle ergometers costing $10,000 to $20,000. The system’s negligible internal friction makes possible a lower load limit of 5 Watts which sets a new minimum limit for electronic bicycle ergometers.

Lifetime Calibration

Velotron is dynamometer calibrated and by design does not require recalibration like ergometers based on strain gauges which drift over time. Using Accuwatt™, you will always know the state of the device.

Accuwatt™ Calibration Verification

Unique to Velotron, the AccuWatt™ calibration verification procedure (patent pending) quickly compares today’s calibration to the time of the original factory calibration to verify that no change has occurred.

Massive Flywheel

Large diameter, 55 lb. flywheel with free-wheel provides an exceptionally realistic bike-like ride including coasting downhill. No knee strain during deceleration as seen with “spinning bikes”.

Electronic Gear Shifting

Velotron uses a fixed ratio chain drive. Shifting is done electronically from the handlebar controller or remote gear-shift lever. The rider can set “virtual” gears to mimic the chain ring/rear cluster combinations on any bicycle – up to 30 gear changes (3 front/10 rear).


Velotron is controlled by system software which runs on Windows XP through Windows 8. The software has two distinct functional modes: Ergometer mode and Bicycle simulation mode. Watts, cadence, heartrate, speed, distance, time and calories are displayed and recorded for instantaneous, average and peak values. SpinScan™ pedal stroke analysis measures biomechanical efficiency. Features include programmable workload protocols, motivational 3D bike courses, two-person races, performance recordings.

Optional Software and Accessories


  • Wingate Testing – Determine your leg power and capacity with anaerobic tests.
  • RacerMate One software – Coming Soon for Velotron!
  • Varicrank – Use to isolate and measure the effect of crank length on an individual’s
    cycling performance.
  • Laptop PC – a Dell laptop PC preloaded with Velotron software.
  • Aerobars – these can be added to the bike for sport-specific testing on athletes accustomed to riding with aerobars.

Delivery and Assembly

Velotron is shipped fully assembled in a palletized carton for forklift or 4-person handling. Shipping weight approximately 200 lbs.

Two Year Limited Warranty

RacerMate Velotron is warranted to the original purchaser for a two-year period from the original purchase date against defective material and workmanship. Any implied warranties are also limited in duration to two years from the original purchase date. Some states do now allow limitation on how long an implied warranty lasts, so the above limitations may not apply to you.

During the warranty period RacerMate will repair, or at its option replace any part that proves upon inspection to be defective. Products subject to improper installation, misuse, neglect, accident, alteration, or unauthorized repair shall be excluded from this warranty. To obtain warranty service, proof of original purchase date must be furnished.

RacerMate shall not be liable for shipping cost to the factory, consequential costs, expenses or damages incurred by the purchaser. Some states do not allow the exclusion of incidental or consequential damages so the above exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.

Experience the FUN of group competition INDOORS – All Year long !!

CompuTrainer MultiRider systems provide an exciting and technically superior method of indoor GROUP bike training and racing. It’s a great way to motivate people to stick with an athletic or exercise program. A basement, garage, bike shop or health club can double as an indoor cycling center for up to 8 riders at a time connected to one PC through a USB Hub.

Read a Bicycle Retailer Magazine article published May 2007 describing an early MultiRider Center experience:
“Retailers Sell Cycling through Indoor Training”
by Jill Janov


Read P3 – Peak Performance Professionals article published 2013 describing their 24% increase in watts in their 5 month MultiRider training program:
“24% Increase in Watts in the “P3″ 5 month MultiRider Training Program”
by Bob Hanisch MA CDE CSCS| USA Triathlon & USA CYcling Certified Level II Coach| Exercise Physiologist| Certified Diabetes Educator



CompuTrainer users have a blast all year long on MultiRider setups all over the world. You can organize group races and training rides anytime you want. Basements and garages for the home user can even be turned into impromptu cycling centers! Ride with up to 8 people on CompuTrainer’s unlimited supply of courses.

The following thumbnails depict each application found within MultiRider. Click on each picture to see a larger view.



Group Time Trials

With Group Time Trials riders compete against each other as they would in any group ride. With CompuTrainer being recognized as the most accurate simulation of cycling physics you can rest assured each cyclist will benefit from the ride when they otherwise are unable to ride outside. Pace-lines with drafting are all there. See where you are on the course in relation to the other cyclists. See your specific metrics to help gauge performance improvement. And don’t forget the most important thing… Have Fun while doing it!

Team Racing and Time Trials

“Where the Road Meets the Lab”. Team Racing simulates both the authentic and dynamic feeling of riding in a pack – and adds the tactical element as well. Supports up-to two 4-man rider teams racing head-to-head. The winning team can be selected using fastest average time, fastest 2nd rider, fastest 3rd rider or fastest 4th rider. A pie chart style ‘clock’ shows the leading team’s instantaneous time advantage.


MultiRider Coaching

Group Training and Coaching allows for non-competitive group training in which each rider performs at his own level based upon their threshold wattage. This is done by training the individual athletes in ergometer mode — a key feature of the CompuTrainer system. The race administrator or coach will enter an athlete’s threshold value and then create a special “time-versus-percent threshold” test for all athletes to follow. These are similar to the erg files to hold a watt-constant effort. Each rider will be doing the same test, but all at differing workloads!

MultiRider Real Course Video

This application allows you to use the Interactive Real Course Videos in a MultiRider Environment. Unlike other MultiRider events, the video controls every rider, but only one rider controls the video — the lead rider. So the challenge is to become the lead/controlling rider.

Note: Due to the nature of this application, ever rider will have varying course distances. As such it was intended solely for the fun and not to gauge performance, and as such no performance files are saved when using MultiRider Real Course Video.

MultiRider Systems Warranty Period


Warranty for MultiRider Systems differ from “home user” warranties due to the industrial nature of the application. All MultiRider-use CompuTrainers are warranted for a 1-year period for both the electronics as well as the training stand, regardless of indications to the contrary in manuals and other documentation.

For over 25 years RacerMate has developed interactive software for use with CompuTrainer and Velotron. Racermate’s President and chief engineer, Wilfried Baatz, set the strictest requirement for accuracy of information presented to the user, a standard which continues to this day. Our longevity (over 35 years in business) is a testament to his original vision… and assures your investment will provide time-proven results.

When RacerMate introduced the CompuTrainer in 1986 (using a Commodore 64 computer), training indoors was catapulted to an all new level. The concept introduced then, and improved through the Nintendo and early PC years, is now perfected in RacerMate One. This being the ability to save your performance data and use it as a pacer to train against yourself. This single feature has allowed owners to improve in ways no other motivational tool has allowed for; the results of which allow us to offer an unprecedented Performance Improvement Guarantee (PIG) - an industry first. Improve your performance or return the product and receive your money-back.

With every product developed under the technical direction of Mr. Baatz, RacerMate continues to create a unique body of software, both technically accurate and motivational, with the goal being to make it compatible with our pre-existing trainers with minimal hardware upgrades, whenever possible. Your investment in a RacerMate product will not be short-lived by software being intentionally created to be compatible only with the newest products.

RacerMate One


RacerMate One embodies all previous software development wrapped up into one slick new package. No more need to open multiple applications, RacerMate One is the new flagship software designed to meet our future development needs.

The following thumbnails depict each application found within RacerMate One. Click on each picture to see a larger view.


3D Cycling

3D Cycling takes our 3D software, introduced in 1995, to the next level. Add 8 live riders and/or Smart Pacers™ allows a ride like no other. Configure Smart Pacers™ at differing wattages - you can call them into play simply by increasing or decreasing your wattage to match their setting. They will instantly “move into action” helping you to maintain that wattage. Use performance pacers “as ridden” or +/- 30% of the original. Multiple split-screen views and camera angles. What more can you ask for?

Real Course Video

Unique recording process allows Real Course Videos to speed up or slow down with your speed. Courses mostly filmed on race day show the course just like being there in the race!

Spin Scan

SpinScan™ is a key to analyzing pedaling efficiency with pinpoint accuracy. SpinScan™ measures the direct torque exerted on the pedal at every angle of its rotation, allowing for precise rider analysis. The more efficient you are, the faster you can be.

For more information, see SpinScan - Smoother is Faster

Power Training

Power Training will run any course type available; Time/Grade, Time/Watts, Time/%AT, Distance/Grade, Distance/Watts, and Distance/%AT. It will also play back all previously saved performance files to help pinpoint specific parts of your ride you need work on to improve.

Multi-channel display of your metrics can be toggled to display only the channels you want to focus on during the ride.

Will operate as either manual mode or with aforementioned courses.

Course Creator

Introduced Fall 2013 Course Creator allows a user to create courses for any RacerMate One application. It will also allow you to edit existing courses as you see in the image.

Do you have a favorite GPS course? Use a GPX version of it (GPX files can be extracted from GPS using tools readily available on the Internet) containing Latitude, longitude, and elevation (all three components must exist to create a course) and Course Creator will create it in the RacerMate One format.

3rd Party Partners software products to consider


Software developed by our partners will deliver the same results as with our software products. Partners use the same technically accurate algorithms created by our engineers - and not the reverse-engineered (and poorly implemented) products filtering through the market claiming to work with RacerMate products.
