Overview

Get Rolling!

Specially designed to travel with the Brompton folding bike or another very compact folding bike. This version of the Radical Design Cyclone IV Trekking Trailer is wider and shorter and has a black “padded” bag. The wheels of the Chubby have the same size as the wheels on the Brompton.

The Chubby uses exactly the same technology as the multi-prize-winning Cyclone Trekking and Cyclone Cargo.

Travel by bus, train and in some circumstances on planes with your Brompton stored inside the padded Chubby bag. On arrival, just take out the bike, put your luggage in the bag and connect the Chubby to your bike.

Please Note: We recommend the Chubby for travel with a bike where the bike and Chubby are stowed under your supervision. Using it for travel on airlines is risky as the level of protection offered by the Chubby is not sufficient for rough handling. Plane travel is possible with some airlines that will handle the bag with caution or by packing multiple layers of cardboard in between the bike and the bag.

Up to 100 liters of storage in the bag — 6,102 cubic inches. That’s more than twice the size of a standard carry-on bag.

The cyclone is a two wheeler, so it is not affected by the leaning of your bike. (Put another way: the trailer won’t fall over just because your bike did.)

The tow bar connects to your bike’s rear hub for minimal effect on your bike’s handling. Your rear rack (if you have one) is still available for a rear bike child seat, or a bike trunk bag.

Insert the wheels into the rear axle bushings and the Cyclone IV Chubby becomes a walking trailer — and for more convenient towing by foot, use the Radical Design Cyclone Walking Towbar.

Folds for compact storage. TIG-welded frame bushings mean a strong and secure connection of the wheels to the frame, even with heavy loads and high speeds. The wheels are equipped with industrial sealed bearings, ensuring minimal rolling resistance and maximum security.
