Best mountain bike lights: everything you need to know

The world of bike lighting technology is packed with jargon and it can be hard to figure out exactly what you need without spending a fortune. Luckily, we’re here to help find the best mountain bike lights for you.

  • The best mountain bike lights
  • Best waterproof jackets for cyclists

To cut to the basics, the only requirement for mountain biking in the dark is some kind of illumination. Even a basic commuting light can stand in, but you’ll quickly discover that riding can get sketchy very quickly without enough power to light the trail in front of you.

How bright is right?

The temptation is — naturally — to get as much power as possible. And power is good, but there’s much more to the story. If you tend to cruise climbs and cane the descents, you want max power for the sketchy bits. You can then toggle right back to save battery power as you trundle back up. If you’re more into mixed trail riding, you need good lights all the time and battery life is more important.


You may have a 1,500-lumen light, but if the battery means you can only run it at 50 percent power for a fast cross-country/trail ride, it’s less bright than a ‘weaker’ 1,000-lumen unit you can run at 100 percent. Given that battery life fades over time, having the extra capacity means you’ll get more years use from your light.

It’s also possible to have too much power — particularly in wet or foggy conditions, where bounce-back and glare mean you see less than with a less powerful unit. Riders with brighter lights behind you can throw your shadow down the trail, blotting it out.

In general, there’s little that will make you wish you had more power than a good average light produces. You’ll find you adjust to whatever you have and that riders who are faster in daylight are still faster at night, regardless of what lights they have.

What to consider when buying mountain bike lights

Features of a mountain bike light

Head or bars


  • Pro: Light shines where you’re looking
  • Con: Flattens out visible trail features, reduces depth perception
  • Con: Can be knocked off by low trees


  • Pro: Easy to see indicators and operate switches
  • Con: Light only goes where your bars are pointed
  • Con: Drops backside of crests and lumps into shade, so you can’t judge obstacle size

Jargon buster

  • Amp-hour — A measurement of battery capacity. The bigger the capacity, the longer your lights will run. You need to divide this value by the amperage the light operates at in order to get the theoretical run time
  • Bag — A cloth pack that holds the battery onto the bike’s frame
  • Bar mount — Light bracket that fits around oversize (31.8mm) and/or older 1in (25.4mm) diameter handlebars
  • Battery cell — The single units that wire together to create a battery pack
  • Bottle — Plastic water bottle converted to hold a large capacity battery
  • Candlepower — Unit of light measurement
  • Cell — Individual unit within a larger battery block. Most mountain bike light batteries are twin or quad cell units
  • Colour temperature — Colour of the light. The more blue-white, the ‘colder’ the colour; the more yellow, the ‘warmer’
  • Cree — Leading LED manufacturer
  • Flood — Head unit designed specifically to spread light over a wide area
  • GoPro mount — Double-D and thumbscrew set up used on GoPro’s helmet cameras
  • Halo — A distinctive ring in the pattern of the beam
  • Halogen — Best of the conventional bulb types. Cheap and easy to replace, but power-hungry so needs big, heavy batteries. Most manufacturers now use LEDs instead
  • Helmet mount — Bracket that lets you fit the light on your lid
  • HID (high intensity discharge) — A metal halide lamp that uses a tiny but extremely bright striplight bulb that only draws 10W but produces more light than a 40W halogen bulb. Gives that distinctive blue/white alien light of BMW headlamps. Most manufacturers now use LEDs instead
  • Jack — Connector plug on the lead
  • Jubilee clip — Fastener that uses a band tightened with a screw-driven gear wheel
  • LED — Light emitting diode. A solid state semi-conductor that glows brightly when a current is passed through it. The ‘bulb’ choice of most manufacturers
  • Lead — Cable that connects the head unit and battery. Extra long extension units are available for use with helmet mounts
  • Lens — The screen over the LED and reflector that protects them and can also be used to modify the beam
  • Life indicator — Traffic light style colour change display that indicates the remaining charge in a battery
  • Li-ion — Lithium ion. The most expensive but lightest, most efficient battery available. Also the easiest to look after in terms of charging/ recharging and therefore a very good thing
  • Lumen — Often quoted measure of the theoretical power of a light. Thermal issues and management circuitry normally make it an optimistic guide at best, though. With no standard way to measure it for bike lights, most figures can’t be usefully compared
  • Lux — Lumens per square metre. The real light output figure that we generally use in our comparative lab tests
  • NiMH — Nickel metal hydride. Cheaper battery type that’s reasonably robust in a charge/recharge sense but heavier and bulkier than a Li-ion for the same capacity
  • O-ring — Thick rubber band used in some handlebar mounts
  • Peripheral — The outward edges of the field of vision. Useful for seeing movement in low light
  • QR — Quick release mechanism
  • Reach — The distance down the trail that the light illuminates
  • Reflector — The shaped reflective surface behind the LED that concentrates and reflects the beam of light
  • Seoul — LED manufacturer
  • Smart charger — Charger that senses how full/empty the battery is and adjusts its efforts accordingly rather than burning down your house
  • Spot — Head unit designed to focus light in a narrow, long reaching beam
  • Throw — How far a light’s beam can reach in front of it
  • USB — Universal serial bus. Standard connector for computers
  • Voltage — The power level the battery releases its energy at
  • Watt — A measurement of power. You’ll often see bike light outputs quoted as ‘equivalent to a 20W halogen bulb’ for example

Lapierre Overvolt AM700 Carbon first ride review

Lapierre has shown just how committed it is to the burgeoning yet controversial electric-assist mountain bike category by investing heavily in its latest e-MTB, the Overvolt AM carbon. We took the cheapest of the three bike line-up for a spin on its native trails in Dijon, France to see just how Lapierre’s new take on e-MTB design shapes up in the real world. Here’s our initial impressions…

  • Lapierre aims to make Overvolt ‘as playful as a non-e-MTB’
  • Lapierre Overvolt FS 700 review

Lapierre Overvolt AM700 Carbon: highlights

  • All new carbon frame shifts the battery position as low as possible
  • Convertible between regular 27.5in and 27.5+ wheels
  • 150mm travel up front and 140mm of travel at the rear
  • Uses Lapierre’s proven OST+ suspension platform
  • Features Lapierre’s new internally routed dropper post
  • Aggressive geometry

The frame: how low can your battery go?

According to Lapierre, creating an e-MTB out of carbon was never about weight saving. No, this was all about how its engineers could package the hefty battery and motor in a bid to create an e-MTB that handled more like a regular mountain bike, lowering the bike’s centre of gravity and injecting some of the nimbleness that e-MTBs are often a little short of.


In the end, Lapierre managed to lower the 500Wh battery a whopping 72mm in the main frame, rotating it and plonking it just above the Bosch CX Performance pedal-assist motor.

The slack 66-degree head angle certainly gives you an idea of what Lapierre had in mind for the Overvolt AM700 Carbon when pointed downhill. Meanwhile the effective top tube on our medium test bike was a reasonable 600mm, though the 415mm reach certainly isn’t the longest out there. Lapierre has also opted to use a 5mm bottom bracket drop coupled with slightly shorter 170mm FSA cranks in a bid to get the right balance between ground clearance and cornering prowess.

If you’re still unsure whether you’d prefer to run standard wheels or try out the new plus-size option, you’ll be pleased to hear the Overvolt AM will happily accept either, courtesy of the DWS (Dual Wheel System) dropouts and Boost axle spacing at the front and rear. Flip the dropouts and simply slot in your preferred wheel/tyre combo. It’s worth noting that Lapierre will be selling separate wheel packages should you want to try this for around €300. Switching between 650b and plus will grow your chainstay length by 10mm though, stretching it from 475mm to 485mm.

Thoughtful spec choices and excellent own-brand dropper

Bulls Outlaw first ride review

Bulls’ Outlaw is billed as a hybrid, but there’s more to it than that. With the minimal tread 27.5 x 2.4in Schwalbe Super Moto-X tires, it’s definitely a tarmac machine, yet add in the tough alloy frame, 120mm Revelation fork, and SR Suntour battery and motor, and the lines definitely begin to blur. Is it the machine to turn your commutes into something more? 

  • 10 reasons you should try an e-MTB
  • The real problem with e-MTB
  • Electric bikes explained

Bulls Outlaw spec overview

  • 7005 alloy hardtail frame
  • RockShox Revelation RL Solo Air, 120mm
  • 27.5in Ryde wheels with Schwalbe Super Moto-X 2.4in tires
  • Shimano 10-speed drivetrain
  • 203mm Tektro Dorado discs
  • SR Suntour 670 watt-hour battery
  • 70 mile range
  • 28mph top speed assisted
  • 3.5hrs charge time to 80%, 5.5 hrs to 100% (approximately)

Bulls Outlaw ride impression

The mountain bike geometry, combined with the big, round-profile 2.4in rubber makes for a carve-happy, surefooted urban machine. Potholes, busted pavement and the occasional dirt path are all mere afterthoughts on a bike like this. I enjoyed every corner on this rig, mostly due to the aforementioned qualities, but also the pull of the SR Suntour motor. With four modes to choose from, it was pretty easy to start with minimal boost (eco mode) to get a feel for the torque. Once accustomed, bumping the setting up to Climb mode adds substantial kick – and makes looking ahead out of corners a much bigger necessity. 

All that fun does come at a trade off of pure speed. The fun seating position keeps you in the wind, and increases aero drag significantly. The suspension fork may feel like overkill if you’re simply trying to get to work on paved surfaces, and the wide, heavy tires aren’t going to win any rolling contests.


But that’s not what this bike is about. I could see myself mounting up some proper knobbys and taking this on the dirt. The frame, fork and components, especially the wide rims, are more than ready to do just that. 

Bulls Outlaw vs the competition

The Outlaw, which costs $4,000 / €4,200, occupies somewhat of a niche space in not just the e-bike market, but the general bike market as well. It’s very simple to slap on some Schwalbe Super Moto-X tires on any e-assisted hardtail, but not many companies are offering what Bulls has done here out of the box. That’s what makes the Outlaw unique, and so much fun. 

Early verdict

Bulls’ Outlaw makes me want to carve corners and see how far I can dip the bars over. Its silhouette and riding position remind me of a rowdy hardtail mountain bike. It’s likely a good thing it has a battery and motor, because I can see every ride getting longer as I seek out the best corners and features to ride.
