How to choose a power stairs climbing wheelchair that is perfect for you?

When it comes to choosing a power (or electric) wheelchair, it’s very important to choose the right device that will meet all your needs. We have compared four popular models to help you choose the one that can provide you the best experience.

Scewo Bro

Scewo is a beautiful example of modern and ergonomic design. Its main advantage is speed and compact size. It can not only climb stairs but also to elevate a user about one meter high. The chair can be controlled from a smart panel or from a mobile device and have a built-in rucksack for personal belongings, which makes it a great friend in the city environment.

TopChair S2

TopChair is a more advanced city wheelchair – it has great back support, a lot of tilt options and self-leveling seat. The front independent shock absorbers that help to neutralize the road bumps and the remote infrared sensors are providing the information for automatic step detection and wheel retraction system to easier navigation. It has an impressive motor that allows the customer to be able to wander for 35-40 km (distance depends on the weather, road quality and the weight of owner).

B-Free Ranger and Flash

B-free Ranger is the one with the biggest size in our rate. Its main specialty is rough terrains and stair climbing. The chair uses the innovative “hook and step“ technology, which provides a more secure and stable stair climbing. This way it can climb to very different types of stairs with different sizes and inclines up to 35 degrees. Also, they provide a smaller version called Flash, which has a smaller size and is suitable mainly for the wheelchair-friendly environment. Both models have the option to be manually moved with the help of an attendant.

B-free Ranger


The Caterwil’s strongest feature is a safety. It has four caterpillars that ensure 100% safe climbing even on high steps. The climb stairs option shows impressive results not only on the high inclines (up to 40 degrees), but also in the different weather conditions. Designed for use in the conditions that may not be wheelchair-friendly, it provides the best experience for people who need to use the wheelchair in the narrow spaces on the constant base. In the default built the size needs to be manually adjusted, but there’s an option to add the power seat which allows the user to adjust it independently. If needed, it can be easily upgraded to be used in the attendant mode. The Caterwil chair is suitable for all types of people who can operate the chair with a hand.
