Yes works really good. Best bit of bike tech I have

Yep really good bit of kit - feel lost without mine now.

In built up areas where there is a lot of traffic it can be annoying more than useful. When riding on country lanes however I wouldn't ride without it, picks up cars that you wouldn't know about with wind noise etc. Genuinely the best gadget on my bike, I ride a lot on country lanes and allows you to ride primary until the car gets halfway up the screen, then ride secondary when the car is passing.

What kind of distance can it pick the car up from? I also ride a lot of lanes but I find that cars approach too fast in most instances.

Same price on Wiggle and for a new email address you'll get a £10 voucher to discount it to £119.99

I have the first gen version of this and agree it is brilliant. Very accurate and reliable.

I really want one - Ive seen these in action and they are just amazing

I only ride in the city, so take it this wouldn't be any more useful than my wing mirrors?

Correct - plus you can hear cars pretty well at city speeds (below 15mph). It’s really only on country lanes you need this, when you can’t tell wind noise from car noise

This, plus the fact that it tells you how many vehicles are behind you as well, something a glance over your shoulder or even mirrors don't always tell you immediately.

I'm lost... alerts you that there is a car behind you so you can do what exactly?
Don't see that it makes any difference unless you're going to turn in which case you should look over your shoulder anyway.

Will Halfords pricematch and then add the 10%BC ontop?

I know there isn't a time machine but this has been 90 quid

No, it's one or the other.
Unless you get an assistant that doesn't know what they're doing.

Two things I'd recommend when using the radar.

1. Make sure you tether it to your bike. Mine has "fallen off" multiple times.

2. If you already have a rear light or just want to save battery power, install this app:
apps.garmin.com/en-…1c4
It will allow you to switch off the light module of the unit and use it as a radar device only.
The app also has a battery gauge, which you can add to your data screens.

I've found that Halfords seem to scan Amazon prices and automatically price match after a day or two (at least they were when I was monitoring Garmin Vivoactive 3 prices).

Once they've done that you can use BC 10% no problems.

An assistant that doesn't know what they are doing....in Halfords....

Think you will be fine

Now at Halfords for £129.99 so can get the 10% as well

Exactly, what would you do when it tells you there is a car behind? Jump on the kerb? Slow down? There are plenty of people who like this gadget from reading the comments but I'm fairly surprised that none of them has tried to reply to your comment.

Has anyone used this with a Garmin watch, rather than an Edge device? I've got a 935 with bike mount, and I'm wondering if it works as well?

That's deep... need to get off the bitty mate

Will this detect motorbikes too?
Just in case Mr. Stealth is out and about on his bike in-between commenting on push bike deals....

Yes, detects motorbikes too ‌

I ride down country lanes frequently but don't see what this unit gives you. If you ride in a group I can see it might help. Genuine question what I am missing about its usage? The only circumstance I can see it helping is if I am cycling up a hill and getting tired and my riding is getting a little ragged then it would make me correct my line sharpish.

Imagine this.
- You want to be tucked in using the most aerodynamic position on your bike, which means being on the drop part of the handlebars, it's hard to look over your shoulder whilst on the drops.
- You also want to be using the least potholed/patched part of the tarmac.

So with your head down and not riding in the gutter you can get a few extra km per hour and then this will alert you if a car is coming so you can move to the left.

I frequently take advantage of the bridge of the road on country lanes because it's so much quicker and more comfortable

That makes sense but I don't ride like that.
