    On some scooters you have to remember to brake/stop your scooter. You don't want to be out riding and forget to hit the brakes so you hit something and cause a terrible accident! Our ElectroMagnetic brakes automatically stop your scooter completely so you don't have to worry about that!  This is designed to lower the chances of accidents and injuries for your maximum safety.

    Electromagnetic brakes are the safest brakes in the industry.  When you let off the throttle, it automatically activates the brake system.  It is a safe way for the rider to stop by giving a smooth slow down to a gentle and effective stop

    Not only are the brakes Electromagnetic but they're also regenerative. Figures provided by experts states that regenerative brakes are around 60-70% efficient. More than that, because regenerative braking systems rely on the motor itself more than they do separate components, the brakes are far more durable and require less frequent maintenance


    We've heard countless horror stories of our customers being out on a family day out and all of a sudden, POP! Their wheel got busted and it completely ruined their family day out because now they aren't able to get around anymore. Not to mention the headache of repair cost for your new tires. You don't have to worry about that at all with our Anti Flat Tires! Never have to ruin your day ever again because of a flat!



  • The average mobility scooter on the market goes on average 10 miles per charge in distance. Not your S331 Pioneer 9. Among one of the longest distance in the entire industry, your Scooter's drive range can get up to 32 miles per charge. That's equivalent to over 480+ Football fields! Before you decide on another scooter, think about the longest commutes you'll have. Think about a long day out at the zoo, or even amusement parks with family. You want to make sure you get the perfect option to suit your needs for long distance rides so you never have to worry about running out of juice and being stuck somewhere, having someone push you around.
