This may be little, but it's mighty. The Raptor Aero simply latches onto your 1" to 3" diameter downtube and won't let go. And with the ability to leave your bike's wheels on, it's as quick as it is unassuming. Weight: 7.40 lbs. Dimensions: L 52.00 in x W 9.00 in x H 25.50 in.

CARRY COMPLETE BIKE: A great option for bikes with traditional frame geometry and bikes with fenders; No front wheel removal necessary.

FITS MOST BIKES: Fits 1' to 3' diameter downtubes; Accommodates disc brakes, thru-axles, and full suspension; Carries 1 bike up to lbs. at minimum 16' crossbar spread.

ROOF RACK REQUIRED: Crossbar spread must be between 16' and 38' for carrying 1 to 2 bikes (18' to 38' for carrying 3 or more bikes); Fits Yakima round, square, factory, or aerodynamic bars.

SMALL BUT MIGHTY: Lightweight construction and a streamlined profile; RaptorAero is as easy to use as it is unassuming; Tool-free installation.

PROTECT YOUR GEAR: SKS (Same Key System) locks (sold separately) can be added to lock your bike to the mount and the mount to the base rack.

I have a Mazda CX-5 with factory roof rack and cross bars. Will this model fit those?

Yes I bought 2 and love them. I actually bought the 1st one from the dealership. I also have a cx-5.

Will it fit a 2008 Levus is 250? With 29 inch bike rim size?

This rack should fit any car that has 2 crossbars on its roof. And yes, I have racked a mountain bike with 29 inch wheels. Check your make/model at http://www.yakima.com/shop/bike/roof/raptoraero.

How do you keep the rack from being stolen?

Don't leave it on 24-7. Remove rack when traveling in uncertain areas.

Good for 16 and 20 inch kids bikes?

Mine is 24 and 26 Inch bikes and I would say it will fit the 20 inch bike. I do not know about the 16 because I do not have one, it is a really nice bike rack. Hope this helped you a little bit.
