The rear-facing radar keeps you informed on the traffic situation behind, notifying you about cars from up to 140m / 459ft away. But it is well beyond what is really necessary for being seen - during testing I never felt the need to run the light on full blast.
After ranking each light for how well it illuminates the road and its surroundings, it's interesting to note that lights with higher claimed lumen output aren't always better at lighting up the way while you're riding. For example, the Garmin Varia radars will literally make you aware of and track cars as they approach, while the CatEye Sync range allows you to switch on multiple lights at the push of one button.
Despite being used on the fork leg for riding LEJOG, we had no issues with the light remaining steadfastly in place.
The front throws out a good spread of light and in flashing mode easily lights up road signs for a few hundred metres ahead and the rear daybright mode is searingly bright. There is also longer thinner Blinder V version available but we found the on/off switch harder to access than on the standard Square-shaped Blinder. We feel this was largely due to its skinny profile and the amount of force required to fit it to a chunky road bike handlebar - which we feel it needs to b able to withstand.Purchasers of electrical or mechanical items are advised to have the items checked by a qualified electrician or mechanic before using them. It’s simply not bright enough for bombing along at Tempo / Zone 3 through the still of the night - but it is plenty bright for riding at an Endurance / Zone 2 pace on even the darkest roads. The flash settings do give you longer run times but, when riding at light, in many countries it’s a legal requirement to have at least one constant rear beam.
The mounting system is one the best I’ve ever used, with a thick silicone band that holds the light firmly in place (and on a variety of seatpost depths). New bikes are sold with reflectors (and you can read in detail about the legal requirements relating to reflectors here) but regardless - if you're riding at night, using a proper set of bike lights is really an essential.There are more innovative products appearing all the time, so do enjoy exploring the world of cycle lighting. Even the lowest constant setting at 35 lumens - which is still brighter than I think is necessary - is only 3.
hours and can be connected to a remote switch to control light modes from the handlebars while in the saddle. There's every chance you'll drop your bike light from time to time when wrestling with the elastic strap on a cold, dark evening. But we can attest that even the lower flashing modes are bright enough to light up road signs from over five hundred metres away easily. We tended to use the “enduro” mode most, which pumps out a solid 250 lumens, and lasts for around six hours. Only in the two brightest modes does it take on more of a spot pattern, highlighting a smaller but brighter patch of the road ahead.You just cycle through the five modes by short-pressing the on/off button and it’s the standard long press for on and off. I would recommend any StVZO front light made for ebikes (to be powered by the bike battery), especially from one of the big brands as mentioned upthread.
