I’ve looked through this site and couldn’t find a question asking the same. Sorry if this is a duplicate. Also, apologies as I’m posting on phone.

Are there any bike light sets that don’t rely on the o-ring design to attach them to the frame?

I hate having to fumble with o-rings every day when taking my lights on or off to charge. I would rather have a design where the mount is attached to the frame and you simply slide the light into it to hear a click alongside a quick release. Does such design exist? Or something similar that doesn’t involve taking the whole thing on or off?

    Yes - but this is kind of a shopping question. Simply check the "Lights" category on your preferred bike shop website and look at the pictures. The o-ring design is cheaper to make hence its popularity, and modern LED lights with lithium batteries are lighter nowdays, so need less force to hold them securely. For example, Cateye seems to have an affordable dial-adjustable strap design.

  • I replaced the O Ring mounts on some lights with mounts from my old Halogen Vesta night lights, left over from the days of 10W halogen bulbs and NiCad batteries

  • You should be able to find such lights at any bike eshop. They are not rare, if somewhat less common now. Mar 21, 2021 at 14:39

To give a brand neutral answer: all the big light brands have at least some o-ring mounting styles now, but some of them still offer clip-in brackets as optional parts for the same lights. And there are still some around that come with that type, but it's the kind of brand-specific thing that changes a lot and so is off-topic here. So short answer, find lights you like or already have, and look at the spare parts options offered for them.


Sometimes proper mounts are available as separate parts. Busch+müller offer a nice mount for the crown fork for their battery powered lights. Lezyne offers a solid plastic mount (with hex key) for their STVO light (the rubber strap it comes with is total crap).

That being said, some small&lightweight lights come with good rubber straps which work well enough. I keep a USB powerbank in the basement to charge such lights without taking them off.

Generally you can get a good idea by looking at the pictures.

Yes, there are. Any decent StVZO compliant light from any quality German manufacturer can be attached not only to handlebars but to also the fork crown. None of those attachments rely on O-rings as that would be stupid. The whole idea of StVZO is that the headlight beam pattern must illuminate the road but not make oncoming drivers and riders blind. Thus, the headlight angle needs to be very carefully adjusted. With O-rings, that adjustment would not stay set as a minor touch to the headlight such as to remove a battery headlight from the handlebars would alter the angle.

The very best of the lights are powered by a hub dynamo (on a regular bike) or the e-bike battery system (on an e-bike -- it would be ridiculous to convert e-bike battery electricity to forwards motion and then re-convert the very same forwards motion again to electricity on a hub dynamo).

Many of the hub dynamo lights have a standlight so you get light for 4 minutes after stopping. Also quality hub dynamo lights don't flicker like the cheap ones do. You may also find many lights available with an automatic environmental brightness based sensor to toggle on and off the light based on ambient light level.

I think you'll find that some of the lights are powered by a battery. They are a poor solution. They need constant recharging and you need to remove the light every time you leave the bicycle locked so it won't get stolen. A hub dynamo light does not require recharging and is unlikely to be stolen.

Also if your fork crown has fender/light attachments, you want to attach the light there. The reason is that the lower the light is, the more shadows obstacles make so with a low-mounted light you are more likely to see hazards on an uneven road. Mounting it even lower, on a fork blade, could be done but then your wheel makes a nasty shadow on one side so that's not preferred. So that's why all quality lights attach to the fork crown as a first option and the handlebars only as a second option if the fork crown doesn't have the attachment point.
