BikeCityGuide Finn



Very clever, simple and reliable way of fixing your smartphone to your bars, but no weather weather protection.

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.

The BikeCityGuide Finn is a very clever piece of silicone that fixes your smartphone to your handlebars.

You may think you have no need to do this, as your Garmin already tells you how far you've been and where you're going, but sometimes when you need to nip down the post office in an unfamiliar city, it's pretty handy.

This is by no means the first such device, but it is certainly the simplest we've come across.

As the cliché says, sometimes the simplest ideas are the best, and there is no shortage of complicated solutions for fixing things to handlebars, mentioning no names.

The Finn has no screws to tighten, no different clips to suit different phones, it's just a strap made of stretchy silicone.

When you take it out the packet your first reaction will be, "I'm really not sure I want to entrust my £500 phone to this."

Happily, the makers have anticipated this and made a nice little video showing a chap jumping his bmx around in a carpark with a phone stuck on his bars.

Quite why you'd need your phone visible while honing your street skillz in the multi-storey is perhaps open to debate, but the point is well made; if this doesn't dislodge your iPhone then it's unlikely road or trail riding will either.

Installing the Finn is quick and pretty easy, although it feels like you need three hands the first couple of times. You wrap it around the handlebar, threading one end through a slot in the other, and then stretch out the ends to go around the top and bottom of your phone.

You have to pull quite a bit to stretch it around the phone and you find yourself worrying that it might snap, but the silicone is very stretchy and fits round even quite large phones (such as the HTC One).

Once it's on, it holds on a treat.

To begin with you find yourself keeping quite a close eye on things, ready to snatch your phone in case the Finn lets go or snaps, but once you've been over a few bumpy bits and everything stays in place you quickly become more confident.

We've used the Finn on long rides where the roads were sometimes pretty broken up and there was never any concern about failure.

As the phone is not encased, you can still operate the buttons and the touchscreen, and you could even answer the phone and talk if you weren't going too quickly.

So, it's late autumn, we're in England - let's talk about the elephant in the room. The Finn gives precisely no protection at all from the elements. If it's raining, your phone will get wet.

Perhaps you're lucky enough to have a waterproof smartphone like the Sony Xperia Z, but if not, you'll probably only want to use the Finn if you've checked out the weather carefully beforehand.

We did try using it with a waterproof case (/content/review/78077-donkey-label-pack-animal) which worked fine. We were a little worried the edges of the case could wear away at the silicone, but this didn't seem to be a problem at least in the short-term.

Almost everyone carries their phone with them when they're riding now, whether to record their tilts at Strava segments or just so they can be reached by their other half to ask if they'll be back for lunch.

However, most people are quite happy with their phone in a pocket, so do you really need it mounted on the handlebars? Checking your email or the footie scores while riding is not recommended, so the main application will be for navigation.

In my own experience, the time when I most use my phone for continuous navigation is when riding in a city I don't know that well.

I found myself on a Boris bike thinking how useful this would be, although sadly the huge chunky plastic handlebar covers on Boris bikes (and their equivalents in Paris and New York) would make this impossible.

The makers of the Finn started out offering city guides for cyclists. These are available for more than 30 cities across Western Europe so far and give you off-line turn-by-turn navigation aimed specifically at cyclists.

They also include cycle tour routes for those exploring the city without a particular destination. Each Finn comes with a code for a city guide worth €4.49.

Even if you don't want the included city guide (there are none in the UK or outside continental Europe yet), the price of €12 (£10) including shipping seems pretty fair to us.

I've just got around to ordering one. I'll let you know how I get on with it.

Also, thanks for the pics, badkneestom. Useful to see how it mounts. I have an 'out front' tube mount that I'm hoping to strap the phone to. Should make it nice and central and out of the way of my lights and cables.
Forgot to say before that I hate the bulky phone mounts that you typically see but this sleek mount looks like just the ticket  1

BikeJon | 10 years ago

I've got an excellent 'Lifeproof' case for my iPhone 4S and now have just ordered one of these mounts. Looking forward to see how it goes. My Garmin 705 took a tumble (my fault) and has a broken screen but the above could be a reasonable solution whilst I decide what to do about my Garmin.
I managed 2hrs on the bike losing only 8% of battery but that was with the screen off. I've got a boost pack coming to cover me for longer rides but I suspect nothing will beat the Garmin.
Will report back...

Mine arrived today - 3 days from order to door. It's as good as I expected - even around an oversize roadbike bar with tape. See piccys. Unlike a Quadlock no, you can't pick the bike up with it, but having bounced the bike around a bit and seen not a hint of wobble, I'm 100% confident the phone is going nowhere.

It works equally well on the stem in 'landscape mode', freeing up handlebar room for other stuff like - er - hands. You'd need to pay attention to the stem cap and steerer cap, if they protrude a bit, as the phone could rattle against them, but as I rock a 110 it's not an issue.

Genius. Would make an excellent stocking filler or corporate giveaway.

My full review here: including video of using as a bikecam.

1. Ziploc bag - waterproof to the point it's seen me through a monster storm, touch screen still works, visible.
2. HTC One rocks
3. Otterbox rocks
4. I want this so bad.

I do have a waterproof phone (second-hand Xperia Acro S, so rather cheaper than a Z), and it doesn't fit in the Topeak waterproof case I had for my previous phone, and I do sometimes use Maps or Velox, so this looks quite attractive. Shame the city guides don't include UK yet.

It's certainly neater than something like this but possibly more wobbly.

KiwiMike | 10 years ago

Done. Ordered. What a genius solution.

First step will be to give it a damn good wrenching about to make sure it's solid - but I imagine they have done a load of testing - they'd only need 1 in 10,000 to fail for people to never trust it.

Brilliant northernbike what a great idea. And cheaper than a garmin

mbthegreat | 10 years ago

It doesn't protect against weather weather, but will it keep off regular weather?

I just mount my laptop on the handlebars which means I can close the top if it rains. I also find the 19 inch screen easier to read.

Clever people can also build their own functionally equivalent phone mount using a 10cm section of MTB inner tube and a pair of scissors.

I'm sure I'm not alone in being a cheapskate and using my phone as a maps/GPS recording device. This does look rather handy.
