Bike Eye bike mirror



A great improvement over the original, very clever concept

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Bike Eye is a visibility aid that now comes in a second version, making it a suitable option for all kinds of bikes. However, the concept still relies on a clear, uninterrupted field of vision along the top tube so kitchen sink tourists and anyone else who uses large panniers and/or a big saddlebag will still need to look elsewhere.

You can fit it in under a minute using the supplied cable ties, and the softer plastics now used ensure a seamless, sculpted fit around most head tubes. They also insulate against road shock (one of our gripes with the original design) while the newly integrated nut and bolt make for easier alignment than previously. The mirror itself is unchanged, working to the same principle as a car rear view mirror, there is now though a new 10mm wider version available too. The flat glass plate won’t tarnish or peel and it provides better perception of approaching vehicle speed/ proximity than a convex design. When correctly set up it works by giving you a view between and under your legs - optimum viewing point is when your leg is at the top of the pedal stroke.

Setting the mirror in double-sided foam tape safeguards against splinter injuries in the event of a nasty spill. Both versions of the Bike Eye are beautifully simple to use, demanding the slightest split-second glance to see what's going on behind. The performance of the two different versions is neck-and-neck until we come to trailer and tag-along tugging. The original will suit those with the carefully laden low-slung slung BOB Yak genre whereas the bigger surface area wins hands down when habitually hauling box types.

A quick glance from my right eye was sufficient for most conditions so it's a boon for those with compromised mobility in the neck or shoulders. Twenty litre panniers on the rear rack had negligible interference with the line of sight so the Bike Eye shouldn't be rejected out of hand for commuting or weekend touring, but 40 litre models did obscure the view. However, whatever the context, Bike Eye should never substitute for regular over-the shoulder/ lifesaver checks, especially in congested traffic.


Design tweaks make the new version a great improvement over the original; a very clever concept. test report

I bought one at the bike show a couple of years ago. I fitted it and it did work quite well. You still have to look over your shoulder to be completely safe but you can see if something is definitely there or not before double checking/ It's not on my bike anymore. Everytime I got out of the saddle I hit it with my knee. It didn't break mind I just got fed up with it.

I love/hate this mirror after almost 2 years of use. It does work well in practice, but it doesn't have enough waterproofing. The first (narrow version) one I had started to deteriorate in a matter of a couple months. What happens is that moisture gets in between the black plastic housing and behind the reflective surface. When that happens, the silver reflective surface is comprised and is slowly eaten away. So in a matter of a few months it lost about a third of its total area, rendering it useless. The second one, wide version, is doing the same thing although at a slower rate since I put some petroleum jelly in the crevice on the mirror perimeter.

i have been using one for a while now - combined with a shoulder check it is a very useful bit of kit

like over their right shoulder.... the importance of eye contact with motorists behind us should not be underestimated.

For me - this is a waste of money.

I have much better results mounting it lower by the fork crown/headset area. I think the day I converted over to mirror use was when somebody was leaning out of a car window just to slap my ass.

brilliant idea for getting an sneaky view of anyone getting a jump on sprinting for road signs racing
