They're small and user friendly, and there's a new USB rechargeable headlight too

Cateye are launching new GPS bike computers called the Stealth 10 and the Stealth 50 which should be available early in 2013, and there’s a new USB rechargeable headlight called the Nano Shot + coming too with a 600 lumen output.

The Stealth computers aren’t Cateye’s first venture into GPS - they already have the Inou multisport computer – but they’ve never used GPS data for a cyclocomputer before.

They’ve kept things really simple for the user here, particularly with the Stealth 10. This unit is no bigger than a normal bike computer so it’ll sit unobtrusively on your bars or stem.

When you’re out on the road, you get just the data that most people use…

• Current, average and maximum speed
• Odometer
• Trip distance 1 & 2
• Elapsed time
• Clock

The advantage over a conventional system is that you don’t have to have an additional sensor on your bike – just the head unit – and you don’t have to input your tyre size.

The computers store up to 60 hours of data (depending on the logging interval you select) so that after your ride you can upload it all to Cateye’s dedicated Atlas website via a PC. You’ll also be able to upload it directly to the TrainingPeaks site and Cateye are hoping you’ll be able to upload direct to Strava too. Once there, you can check out your performance, look at your routes on Google maps and share your data with others.

The computers should be fully waterproof because there’s no socket to leak – you use a USB cradle for battery recharging and data download.

The Stealth 50 has the benefit of being ANT+ compatible so you can use it with a heart rate monitor strap, a cadence sensor and/or a power meter to get more information. This will be displayed on the screen and recorded for downloading later.

It all looks very simple so if you’re a technophobe who has been reluctant to get into the whole GPS thing before, this could be your route in.

UK prices have yet to be set but, to give you an indication, the US price for the Stealth 10 will be $120 and the Stealth 50 will be $150.

The Nano Shot + is a new Cateye light that has just come to market (we’ve reviewed the Nano Shot in the past).

It comes with a dual beam, has a 600 lumen output, and it’s USB rechargeable. Cateye reckon you get a 1.5hr runtime on high beam and 4hrs on low beam.

There’s also a ‘hyper constant’ mode which is continuous with a simultaneous blinking to get you noticed. This one runs for 2hrs. A three-level battery indicator tells you how much juice is left. This one is out there now and costs £99.99.
