Bontrager's BackRack Deluxe is a smart and capable rear rack with integrated MIK technology, meaning that compatible rear bags can clip solidly and securely into place. Simply as a rack, though, the finish is a bit delicate and it can be a faff to fit.
The rack is apparently both clever and easy to fit. The clever bit comes from the fact that it is designed to accept the mounting system of Bontrager's MIK range of bags – a technology similar to the bar-bag 'KlickFix' system, albeit for rack-mounted kit. As for the 'easy to fit' bit…
The packaging says the BackRack Deluxe is compatible with 18-22in frames. I fitted it to my regular test mule for road.cc tests, an Islabikes Beinn 29. Although it's ostensibly from a children's bike manufacturer, as you will guess from its name, the Beinn 29 runs on full size 29in/700C wheels, has a 20in frame, and fits me: a creature that, physically at least, just about passes as a fully-grown adult male human. That said, the Beinn does have a relatively high rack mount at the rear dropout, and that caused some problems.
The BackRack Deluxe MIK rack comes with unbendable upper mounting arms. I do not have a problem with these in theory, and if your bike comes off the shelf with such a rack fitted, so much the better. However, it's worth remembering that the upper arms are not weight bearing, they are simply there to stop the rack moving fore and aft, so they really don't need to be as strong and rigid as those found here.
In the case of the BackRack Deluxe, if it doesn't fit your bike out of the box, getting it to is likely to be a case of trial, error and some fiddling with the arms and removable receptacles that connect them to the main body of the rack (and which seem to suffer from hyper-gravity, such is the attraction they have for the floor).
If this is the case, once you think you know what you're doing you will need to head to the shed to start sawing away any excess upper arm tubage. Bontrager has helpfully started things off for you with a succession of indents at suggested cutting points along the upper arms. When you've cut them down, you then need to file the ends and bung on the rubber socks to make it all look tidy. Talking of which, treat those arms with kid gloves because, as you saw, the black finish on them and the frame isn't the toughest in the world and you'll find it flaking off with every little ding.
Then it's back to the bike to finish fitting. Except, if you've fitted those rubber socks in a moment of unbridled joy and satisfaction that all the sawing was finished, you'll now find the arms no longer pass through the rack receptacle holes. So you'll have to faff some more, removing the rubber, passing the arm tubes through the holes, and fitting the socks again.
But then it's all done, right? For most people, hopefully yes.
But you'll remember I mentioned I had some difficulty fitting the rack to my bike. The only way I could do it was by sawing at the lowest delineated indent and then positioning the excess arm length in a gap in the rack frame upper plate. I thought it was ingenious, until I tried fitting a Bontrager MIK-compatible bag and realised that the arms now hampered the clever attachment mechanism (as I suspect they might in the pre-test setup shown in our 'studio' photos).
So it was back to the shed to cut some more off of the rack arms and start the merry-go-round again.
Eventually – eventually – it was all fitted.
For all my complaints, the rack itself is actually a nicely made bit of kit. The tubes are svelte aluminium, construction quality is excellent, and, at 650g, weight is in the right ballpark despite the top plate being engineered to be MIK-compatible. There is also a rear-facing plate to fit lights…
…and a cutout just above the lower mounting point gives you somewhere to attach your pannier bag hooks.
Other than in the fitting, there's really not much to go wrong on a rear rack and, once happily affixed to the bike, this is a smart, sturdy and competent accessory.
What can you buy for £39.99? In truth, not much, despite the fact that rear racks are far from the most extravagant aftermarket purchase. The Blackburn Central Rear Rack is an almost faultless option but costs £10 more at £49.99. Slightly cheaper, £35 gets you the Vavert Metro Lightweight rack, although we weren't hugely impressed with it.
If you have a bike that doesn't have rack mounts, Bontrager also makes the sturdy BackRack Lightweight for £49.99. It's possibly an even greater faff to fit than the Deluxe but then, if you haven't got rack mounts, that extra effort is probably the price you expect to pay.
In truth, I'm not a massive fan of firms introducing proprietary technology to products that have spent decades happily doing their job without it – in the case of MIK tech, I would argue it adds unnecessary weight and complication. However, to Bontrager's credit, you can use the BackRack Deluxe MIK with bags and products that don't feature MIK mounts. In any case, the MIK ingredient isn't the rack's biggest problem – that award, for my bike at least, goes to its fitting – but as a straightforward rear rack, it is solid and well priced.
Solid rear rack with MIK compatibility, but the finish is easily damaged and it can be a faff to fit

Nicely made, although the black finish is a little bit on the delicate side and is easily damaged.
Solid and secure.
As a bit of kit, it is tough and will last. However, that finish will leave it looking it tired and old before its time.
In the right kind of area for a solid rear rack. Without the MIK top plate, it could be even lighter.
Actually pretty good value. The Blackburn Central Rear Rack is an almost faultless option but costs £10 more at £49.99. Slightly cheaper, £35 gets you the Vavert Metro Lightweight rack, although we weren't hugely impressed with it.

Bontrager's BackRack is a solid and dependable rear rack that also offers the extra benefit of MIK-compatibility. However, the easily marked finish and potentially frustrating fitting process mean it's far less than perfect.
