Niterider’s Pro 4200 Enduro Remote light is aimed at high-speed downhill riding or backcountry missions, made possible by its 4,200-lumen max claimed output and large external battery pack that can provide up to 16 hours 30 minutes of run time.
Both the battery pack (586g) and head unit (233g) are made from Dupont fibreglass reinforced nylon, meaning it meets the FL1 one-metre drop standard.
The battery is mounted to the frame using two straps with locking clips, while the head unit’s tool-free mount (73g) is compatible with both 31.8mm and 35mm diameter bars, and positions the light directly in front of the stem.
The head unit attaches to the mount using a slide and clip system with a plastic tab to release it.
A single-button remote control is hardwired to the head unit on a 200mm cable. The head unit and battery connect via a 690mm cable, and a 925mm extender cable is supplied, both with Velcro fasteners for attaching to the bike frame.
The head unit’s portion of cable has a secondary port to power rear lights, and the battery has a USB port, so you can use it to charge other devices as well. All the cables are thick and robust.
Both the head unit and remote have a single button that controls the light, switching between four constant modes and three flashing modes. Both buttons illuminate when the light is on and there’s an eight-stage battery indicator on the head unit.
There are six Cree LEDs sitting inside three cone, dual-beam reflectors, tuned to give an off-road-specific beam pattern.
Niterider Pro 4200 Enduro Remote performance
The Pro 4200 Enduro has an impressively focused beam with an intense central spotlight, making obstacles inside this area easy to see, and casting few shadows.
However, not a huge amount of this light bleeds out to the sides, so the beam’s spread is quite limited. Combined, these two elements make it feel lower on lumens than Niterider claims.
The beam has a round shape that is quite large, although its borders are well defined with a hard transition from light to dark; there's no gradual fade like lights with a broader spread have. This makes it suited to high-speed straight-line blasting, where few details inside its reach are missed.
The type of riding you favour, in particular the tightness of the turns, will affect the light’s performance for you.
If they’re not very tight, it’s possible to see around corners and pick lines on the exit, but once the curve sharpens, the exits will regularly be plunged into darkness, outside of the beam’s reach and harsh cut-off.
The upshot of this is that the light isn’t best suited to technical trails, and is more at home on faster, straighter runs, such as at trail centres.
On this kind of terrain, plenty of light is cast ahead down the trail, and there’s enough downward projection to illuminate landings and dips as the front wheel lifts or is in the air.
The beam has a white hue with hints of green, but because of the intense focal point, it can appear quite harsh.
General brightness outside the focal point is less extreme, but there is some 'bleaching' of the terrain at the centre of the beam’s spot.
The remote attaches securely with a double rubber O-ring, and can be set in an easy-to-reach position just inboard of your grips.
Its button is on a rocker, which makes it easy to use. The light’s modes are intuitive and simple to cycle through, via a single push of the button.
Red, rear-facing indicator lights on the head unit tell you which cluster of LEDs is currently illuminated and their power output, which is helpful. Similarly, the battery indicator is clear to understand and provides at-a-glance information.
Battery life was 1hr 7mins on max power in my tests, 20 minutes shorter than Niterider’s claims.
The light mount is easy to attach thanks to its tool-free design. The head unit clips to the clamp and has plenty of adjustment. Its out-front positioning is good, too.
However, there is a fair amount of shaking over rough terrain, which makes the beam look like it's flickering on the trail.
This is quite distracting, and no amount of tightening the clamp stopped it, which was frustrating given the robust feel of the clamp.
The battery pack’s fastening cables are easy to tighten and the cables long enough for plenty of placement options. The in-built Velcro cable tidiers are useful, too.
Niterider Pro 4200 Enduro Remote bottom line
Despite the Pro 4200 Enduro’s promise of high output, a big battery and easy-to-use functionality, I was disappointed with the beam’s spread given Niterider’s claims.
It’s also costly, and in this case, I’d recommend looking elsewhere unless you love the brand or have a dedicated helmet light to pair it with.
How we tested
For our 2021 MTB lights test, we assessed eight units, starting at just over £100 and rising all the way to nearly £500.
Whatever your budget, there should be one that will suit your needs.
Of course, there are plenty of lights available online for less money, but they won't necessarily offer the same reliability or aftersales support as the trusted brands tested here.
All the lights chosen have a minimum output of a claimed 1,500 lumens, but some are much brighter. Generally, more lumens equates to a higher price.
As well as testing how each light performs on the same trail on back-to-back runs – assessing beam pattern, LED colour, ease of operation and, most importantly, light projection – we also timed them all on max power to find out just how long the batteries last, and whether they live up to the brand’s claims.
