Accuracy and Calibration
Everything that makes the Wattbike special can be summed up by the fact that it provides accurate, comparable and repeatable data – something that everyone assumes all bikes that measure power do, but they don’t. The Wattbike is factory calibrated, and will maintain it’s accuracy throughout its life. Other than adjusting your cycling position no setup/calibration of the Wattbike is necessary, and every session is comparable and repeatable The Wattbike is extremely accurate +/- 2% across the range, in individual bands.
<100 Watts up to 6 % or 6 Watts
100- 200 Watts within 2%
200-500 Watts within 1.5%
>500 Watts within 1 %
The Wattbike is measuring real parameters in real time (which sounds silly to say, but not all testing bikes do), it measures the force applied through the cranks onto the chain. As the force on the chain is measured from the rider input, and all the resistance is applied to the same axle of the bike, the power achieved is not influenced by the creation of resistance from the magnetic climb lever, airbrake gear lever or by environmental conditions, so no matter where you use your Wattbike or what setting you have it on you can still have confidence in the data it is providing you with.
It feels like riding a bike
During the production process, once the measurement system had been created we took the bike back to British Cycling for their feedback, and it took another two years of development to come up with a bike that they thought felt like riding on the road or track. The key elements to that is the specifically designed flywheel that maintains inertia so that if you freewheel it picks up where you left off.
Unique Polar view (force curve) to show pedalling technique
This is a major benefit that no other bike offers – the ability to monitor and record pedalling effectiveness for every pedal revolution of every session is extremely powerful. It tells the cyclist whether they have a consistent force profile and angle of peak force throughout every pedal revolution. The right force profile throughout the whole pedal revolution and an even contribution from each leg is very important to getting the most speed out of your physiology. You can see Wattbike Sport Scientist Eddie Fletcher explaining the Polar View in the Training Guide section of this site.
Most people can ride a bike but very few have been taught how to pedal effectively, immense gains can be made by ensuring the right mix of power application, cadence, gearing (resistance level on the Wattbike) and physiological response are selected for the individual and terrain. The Wattbike has been able to dispel many of the myths about pedalling technique and shows exactly what is really happening. This is a major reason why the Wattbike is used by the top cycling teams and nations as part of their training.
Whilst coaches always aim to teach the correct technique it has always been a subjective view as to whether the cyclist is actually doing it. The Polar view ‘exposes’ ineffective pedalling technique and can be used as a tool to improve pedalling technique for all levels of rider.
The Wattbike Monitors Everything (39 cycling parameters – some of which are really only useful in the lab) for a cyclist the main parameters to take note of are:
Power [W]/Power per kilo
Angle of peak force right and left leg
Balance of power contribution right and left leg
The Wattbike offers real time measurement with instant saving of all data for comparison and analysis, it also comes with the Wattbike Expert Software which is probably the most powerful cycling software in the market bringing in depth scientific analysis to all cyclists (and is free).
Replicate any training sessions
The Wattbike can be used to replicate training sessions and provide consistent training performance, whether it is Sprint, Endurance or a combination of the two it can be used for training for all cycling disciplines, and there is never any need to miss a session due to adverse weather conditions.
Training sessions can be specified precisely by power/cadence/resistance (gearing) and HR
Training on a Wattbike is time efficient only needs 50%-75% of time on the road
Sessions can be viewed in Recall in the monitor for post training review/analysis or transferred to Wattbike Expert for analysis, retention, comparison, progress checking
Live recording into Wattbike Expert shows parameters in real time –where the default screen shows pedalling technique, cadence, HR and power per revolution although the screen can be customised to show any of the 39 parameters
The pedalling technique view can be switched live to a very useful real time graph of any of the 39 parameters
The relationship between the cadence and the resistance settings for each power output can be found in the Power, resistance and cadence tables, so it is possible to create any session or physiological demand your training demands. The impact of the training can be monitored through the ANT & ANT + SPORT Heart Rate functionality. It is very easy to structure precise training down to cadence, power and heart rate – link to pedalling technique and our software and you have a very powerful training combination
As if that was not enough you can also download free training guides directly from the website. There are currently two on offer, one for Sportive riders, and the other specific to training for Triathlon. Reference: http://wattbike.com/uk/guide.
The Wattbike can be used as an integral part of any training plan from testing to establishing heart rate and power training zones to very specific training sessions tailored to event specific training needs and skill requirements.
Why not try this session:
Resistance to 4/5
Set resistance to 4/5
200m fast as you can (aim for under 15-20 secs) -50 secs rest -X5
2 min rest after last rep
Set the resistance to 2/3
500m as fast as you can (aim for under 40-45 secs)-75 secs rest -X4
2 min rest after last rep
Set resistance to 1/2
750mas fast as you can (aim for under 60-75 secs) -90 secs rest -X2
Set resistance to 4/5
200m as fast as you can (aim for under 25-30secs) -30 secs rest – X2
2 min rest after last rep.
