At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

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 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.

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.

I got this one today with a new bike. The  intended rack did not fit so they swapped this one in and now I have just found by reading this that there is nowhere for my lights.

Sriracha replied to Hirsute | 2 years ago

But would there have been on the other rack?

Hirsute replied to Sriracha | 2 years ago

All the other racks I have had came with a strut across the back above the flat bit. Looking at a specialized stock photo that one does too. My other bike has black insulating tape wound around the strut to get to the required diameter!
I can see it will be a call to sjs cycles tomorrow. Maybe they will be getting lots of calls !

Sriracha replied to Hirsute | 2 years ago

You could cut a slot in a short section of plastic domestic water pipe and slot it over the rear bracket, secure with a zip tie around the open end (or something neater). Or if you have an offcut of carbon steerer tube the see Welsh boy below.

I have one of these racks, I bought it because they did a small (or maybe they advertised it as short or small or something similar) and I ride a small bike (47-49cm depending on which bike) and the rack fitted just fine, a bit of junior hacksaw use but rock solid and very practical.  I use an old piece of cut off carbon steerer tube with a few holes drilled in it bolted vertically to the back of the rack to mount my light on, though I say it myself it does look rather good.

Here you go, sorry, for some reason the website loaded it sideways

"There is also a rear-facing plate to fit lights…" but I notice you didn't.

Maybe because no existing light in your possession nor any other at Road Towers will actually fit? Yes, I know you could get a German STVZO non-blinking barely-shining 6v dynamo powered light that does fit, and maybe some other obscure (pun intended) battery light from a dusty back catalogue.

But basically, no, these rear mounting plates are useless, except for a reflector.

When will a rack manufacturer realise that back lights need a seat-post type mount? Tailfin seem to be the only ones (and then it's an accessory).

I hear you on this one.

Spent many fruitless hours trying to find a suitable light to fit to my rack.

Can someone Kickstarter an adapter to convert these archaic fixtures to a seat post style mount?

I'm actually surprised they didn't use their proprierary light mountings that they have on the mudguards and trek stems. 

Sriracha replied to AlsoSomniloquism | 2 years ago

Ah, of course! They sell an adaptor mount. Not sure if it is included with the rack, these suppliers show a picture with the light mounted but are coy about whether it's an extra part:
Even so, Bontrager lights only...

AlsoSomniloquism replied to Sriracha | 2 years ago

Probably just a clip thing. TBF with all of those holes and most light fittings being either rubber bands or velcro straps, I suspect anything can be made to fit there although probably not solid fittings. 

OnYerBike replied to Rich_cb | 2 years ago

It doesn't adapt the rack fixtures directly but rather it clamps directly to the rack tubing - but the end result is the same.

Oberon replied to Sriracha | 2 years ago

I use one of these on a rack, from Cateye:

If you don't use or like Cateye lights, you may be able to combine it with this:

Accessory overkill, perhaps, but should get the job done.
