Thule VeloCompact is a compact and lightweight bike carrier for everyday use, carrying up to four bikes. It is the ideal choice for a range of bike styles, including road bikes, ebikes or mountain bikes. Even when the bikes are loaded you still have access to the trunk. Also, with the Thule VeloCompact 4th Bike Adapter (sold separately) the bike rack can be extended to carry 4 bikes. This compact everyday bike rack can also be folded and becomes small enough to store in the trunk of most cars.
