Instead of keep switching assistance levels and speed gears, Pwheel’s three riding modes give you full flexibility and allow you to enjoy your rides in a flow state. Three riding modes are designed for people with different physical strengths and different riding needs, you can easily choose your suitable riding mode on the PikaBoost app.
1.Free Cruise mode is targeting short-distance, commuters because it’s the most labor-saving but the most power-consuming. Pwheel can reduce time spent commuting, reduce your vehicle expenses, and eliminates the chance that you’ll arrive a sweaty mess at your office. Pwheel will always maintain the current riding speed and gradually accelerates to go into full electric riding while reducing speed by detecting the braking mechanism.
2.For people with relatively poor physical strength, ECO mode is your number one option. It will provide assistance only on uphill terrains and can be used on bumpy roads. Pwheel will automatically switch off the motor on the downhill and flat roads and enter the regenerative system hence reducing energy consumption.
3.Even though the Pwheel is an e-bike booster Exercise mode can also achieve a fitness effect on cycling. Pwheel will not only provide any assistance but adds extra resistance for the longest duration. Pwheel acts like a dynamo that can convert kinetic energy into electrical energy thus helping to increase the range which is perfect for long-distance cycling enthusiasts. It can also be used to charge your other electronic devices via the USB socket. In the event that the Pwheel is low on power, the app will alert you if you need to go into Exercise mode, so you can switch to a power-saving state in time.

Our team has put a lot of effort into making the Pwheel ride-ability on all terrains better. These include integrating a self-locking mechanism to avoid loosening due to vibration, and an elastic mechanism to avoid minor laxity that could cause the product to fall off.
More Advanced Sensors
Almost all other products of conversion kits on the market commonly use switch Hall sensors, because it’s much easier to develop and have better versatility. The disadvantage is that it requires cyclists to pedal several cycles to calculate an average speed, and then transfer the speed data to the MCU (microcontroller Unit) for motor power adjustment. In consequence, the response of the motor to the change of speed will be delayed and causes an unpleasant riding experience.
Pwheel uses a two-axis linear Hall sensor. Although the development is more complex, it can detect the speed of the wheel in real-time, thus providing the MCU with the most timely speed data feedback, so as to obtain real-time motor power adjustment, making the speed matching in cycling more smooth.
In addition, with this kind of sensor, users do not need to install an additional set of sensors at the crank to obtain signals.
Exclusive Intelligent Attitude Algorithm
With the built-in two axis linear Hall sensor, Gyroscope, accelerometer and PikaBoost’s exclusive attitude algorithm, under the control of MCU, Pwheel can detect the speed and attitude of the bicycle in real time, judge whether it is cycling uphill, downhill or on the flat road, and whether there is a trend of acceleration or deceleration, and dynamically adjust the output power of the motor for speed matching, so as to provide a smooth transition when the speed changes or keep the bike at a constant riding speed.
