With the depressing thought that its already getting dark earlier, a young man's thoughts turn to rear lighting. I need a rear light to fit the seatpost of my Dahon Mu. I need to remove it too. I am on lit roads and journeys are usually 40 mins. I have read the reviews but a lot of products dont actually fit. Even when the spec says they will.
Any recommendations for a sensibly priced rear light to fit my seatpost?

How about something like the Serfas Thunderbolt? I have two of them, and they are VERY bright. I'm not familiar with the dimensions of the Mu seatpost, so I don't know how well they would fit. The straps are stretchy, and they fit around the seatpost of my mountain bike, although I normally attach the lights to my rack or rear stays (depending on which bike I'm riding) instead.

Just to say that if I ride in trafic I newer trust just one rear or front light. In my opinion the rear light is more important than the front since most of us do not have eyes in the neck..

Damn it! You had to remind us?!

I missed a few days this week due to nasty storms rolling through. I couldn't get over the fact how much longer the shadows are at the same time of day from just a few weeks ago.

Good light, may or may not fit your Dahon. I have a regular Superflash (not the Turbo) on my Friday`s seat mast. For comparison sake, it fits at 1.255 in/32mm dia, but that`s as big as it goes. Pretty sure it`s the same mount as the Turbo.

in a pinch you can go rogue and fabricate your own mount

• buy perforated strapping
• cut to length with vise and hack saw
• wrap and bolt to PBSF mount
• adjust and tighten
• light clips in and out easily
• since I've lost PBSFs on bumps, I add the rubber band

^^Looks tough on a very small rack tube like that (good job). It would be much easier on a tube that`s too fat for the stock mounting band.

Have a Rain Cape I throw over myself in the wet weather , so I mounted the lights Low enough to not be covered ..


Hub Dynamo ... already done on the Bike Friday.. about to invest in a new Brompton wheel..

For those who like closure, I bought a Smart Lunar R1. https://www.amazon.co.uk/s/ref=nb_sb_...rds=REAR+LIGHT It didn't fit the seat post despite the blurb suggesting it will. However, it also came with a bracket to fit it to the rear rack. I use Mini Ortliebs so can't fit the light there. Good news, it fits the seat rail (using a lot of the rubber matting it comes with) and is in a great position. It doesn't mess the fold and is easily seen. The light is small, flashy and bright. I still carry spare lights and usually hang one off my panniers, but its great to have the main tail light sorted.
So if you have an MU, a Smart Lunar R1 is an option.

Hi,

That is debatable. You can get way with a well positioned
rear reflector and reflective pedals from the rear but a front
light IMO is mandatory to be seen coming.

rgds, sreten.

FWIW in the UK the 99p/£1 shop lights are surprisingly good.

Agree with you on that.

Agreed... especially since cyclists usually travel in a lane where traffic approaches us from behind. It's foolhardy to not use at least one good bright flashing light.

This is not bad advice. When dark, having spares is a good idea. (When dark out, I run one rear light solid, the other flashing).

I personally mount a Cygolite Hotshot to my helmet (it has a seatpost mount, but I've never used it). It's quite bright and USB chargeable (so it's easy to charge at work).

Had the 1st Rain in months , and of course the 1st Rear end collision happened as drivers were braking late
which they could get away with on dry pavement ,

but wet, with a wee bit of Petroleum weeping out of the summer traffic , getting floated by the rain ,

and the stopping distance difference got longer..

So what I decide to trust or not trust is debatable? Good to know.

What if that one light fail, or fall off?? Just asking.

Agreed, I have one of the 5 led front lights that looks like a torch and its surprising how bright it is. Not suitable for unlit roads although there is enough light to see the edges of the road. They make a good "get you seen" light for town and city riding. Cheap enough to have several on the bike. The brackets break easily so I use a Velcro and rubber mount from Deal Extreme.
