Pretty darn convenient I have to say. Set up for the rigid frame mobility scooter models for towing...your pet pooch? Additional groceries? Firewood? What takes your fancy. This isn't one of those little jobs. This is decent sized trailer. The tyres are pneumatic 20 x 1.75 on 430mm diameter(17") wire spoked wheels. The carrier floor is 720mm L x 520mm W. Unit sits at 900mm high. Weighs approx 11kg. Rated at 30kg payload. Zipper rear mesh grill with straps to roll-up and secure so it stays open if required. The front has the same arrangement but includes a velcroed clear plastic anti-rain cover. Side are meshed grill. Unit comes complete with a trailer arm that can be secured to a bike as well as a tow-bar bracket for fitting to the back of a mobility scooter. And yes - per pictures - a wee safety flag to compliment the reflectors.
