By John Galante
What a great idea ! You ride bike for exercise, but every so often you need a boost. You can buy an expensive motorized bike, but you already have a bike that you like. Here comes the PikaBoost. I haven't tried one, but this is what they are saying.
Is it easy to assenble ? The PikaBoost uses an all-in-one design - battery, motor and controller. You can quickly mount it between the seat post and the rear wheel with no tools. This also means you can easily switch PikaBoost from one bike to another. It makes it easier to use PikaBoost on road, shared and rental bikes.
How is it powered ? The PikaBoost has a maximum range of 30km under the full electric assistance mode. The battery is replaceable. PikaBoost uses 18 cells of 18650 Lithium batteries (3.5Ah per cell), forming 234Wh battery capacity in this 3kg add-on. At a full load level, the range is up to 30km/18 miles, which rivals that of a bulky e-bike.
How is the ride ? Instead of switching assistance levels and speed gears, PikaBoost's has three riding modes which gives you flexibility and allows 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.
How is it different from other conversion kits ? Almost all other products or conversion kits on the market use switch hall sensors because they are much easier to develop and have a better versatility. The disadvantage is that it requires the cyclists to pedal several cycles to calculate an average speed, then transfer the speed data to the MCU (microcontroller Unit) for motor power adjustment. As a consquence, the response of the motor to the change of speed will be delayed and causes a unpleasant riding experience.
PikaBoost 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. With a pledge you can get one for $329. It will retail at $599.
