Cateye Volt 50 rear light

A bit late; done already and IMO better by Exposure.
This is bulky compared to a Exposure RedEye in a saddle rail mount, and may not fit with some rail clamps e.g. the adjustable one of my Cane Creek suspension post.

I also have an Exposure Flare (and spare rechargeable battery) for mounting on a mount zip tied to my rear rack when the RedEye is blocked by especially tall stuff, which would be more likely with this Cateye attempt.

The light spread is excellent for both Exposure lights ; it obviously won't be as good with this Cateye one because the lens is less obvious.

I've blacklist all Cateye gear because I keep discovering stupid design faults and structural weaknesses with their speedos and lights; it wasn't worth the hassle and replacement cost anymore.

Looking at the telemetry of most mountain bikes the only sensible fixing point is under the saddle at the rear; which is a sensible place for other attachments (like a bag with a spare tube/tools etc).
It would be good if bags has a fixing point for a light beneath them,...gap in the market I think!
Also if the front mount (for the Volt300 front light) also has a swivel it could be used on the off-side rear fork as the attachment for the Volt50 (Rear red light) is the same as the Volt300 (Front white light). The front (Volt300) brackets are only £6.95 or so and easily available,....almost but not quite!
...
Perhaps I'll put a suggestion into Cateye!

There is a seat post bracket for this light (SP-13) but none of the major retailers seem to be stocking it at the moment.

I have the light and its front counterpart and am really impressed with both of them. The saddle mount is a different matter though...

Mine came off during a dark and very wet commute home, no doubt rattled free by the potholed winter roads. It didn't seem to be loose when I attached the light before setting out either, so keep a close eye on it if you use one.

A clubmate has this light and the Cateye 300 front. Smart looking kit, he liked the idea that you can swap the batteries over if the front gets low.

I was driving through town and caught him up. Pulse mode was really effective - the light was already bright enough but the extra pip of red every few seconds was really noticeable, even when the bike was 200-300 metres ahead in traffic.

Like this reviewer, I didn't fancy the bracket. If you want an under-saddle solution then consider the Cateye Rapid 3 or TL-610 (both use AAAs) with the RM-1 saddle rail mount.

I was commuting home last week and got stuck behind someone who had this light on. Fairly gave me a headache.

Until I passed him

Would've bought one of these to compliment my Volt 300 front light, were it not for a set of circumstances that resulted in me only being able to get a rear light from a retailer who didn't stock Cateye lights.

Not too fussed about the mount myself, I ride a "normal" ride bike and don't carry a saddle bag, so no concerns there. Can appreciate the Marmite analogy though, it's not for everyone.

Went for a Lezyne Micro Drive instead, about the same price as this (in terms of what you'd actually pay, not the RRP) and am quite impressed with (the output of) that. It's the newer version with the revised mount, haven't had any problems with it popping out in a couple of months of riding with it now.

Consider a RB with Aero seat post, normal rear light cannot be mounted on the teardrop shaped post. Saddle rail mount is the best option of these bikes.

The output is excellent, I've had a couple of comments from drivers how visible it is. It is very easy to use too with a simple cycle of options and enough of a delay not to accidentally be turning it on or off.

It is pricey but I've never yet seen one as much as your stated £49.99, I think you may have got the price mixed with the 300 front light. The average price for them is £10 less than you state and mine was £29.99 from Evans recently.

My gripe is the bracket is a tad flimsy. I have managed to crack the housing for the nut with very little pressure and no feedback or warning I was overtightening. It is secured with superglue now and seems solid enough.

It took a lot of cursing and cussing to get the bracket to fit the carbon rails on my saddle.
Love the light though, plenty of light given out on the unlit country roads that I commute on.

Agree, if you're on a TT bike, your saddle is more than likely going to be pushed fairly far forward. My summer bike has an aero seatpost and I recently bought a rear light based on the fact that standard mounting systems aren't compatible. I have an inline post, with the saddle fairly far forward so this Cateye wouldn't fit. I went with a Moon Comet http://www.moon-sport.com/product-detail.php?id=72 The battery doesn't last that long, but it's long enough to be out for 3hrs in the evening, or a long early-morning commute, perfect for a TT bike. The under-saddle mounting is also really tidy compared to the Cateye bracket and isn't that noticeable when the light is removed.

I bought one for exactly that reason but the damn thing is so long it won't fit past the mahoosive seat post on the Dean.

Seems great for early morning training on the TT bike, as a light basically won't fit anywhere else but the saddle rails thanks to the funky tube shapes.

Was also thinking about the Exposure Flare, which got a good review but comments from longer-term users turned out to be a fair bit worse: http://road.cc/content/review/46514-exposure-flare-rear-light
