Lights for eBikes, See & Be Seen!

https://electricbikereview.com/forum/... While visiting my buddy Chris Nolte at Propel Bikes in Brooklyn, NY we spent some time talking about bicycle lights. Chris runs an electric bike shop, so most of the models we looked at had the option to wire-in some lights to run off of the ebike battery. Some of these lights would work just fine on their own, being powered by independent rechargeable cells. Many electric bikes come with lights already wired in. I hope this guide helps you understand why lights for bikes are important, what some of the options are, and why ebikes can be a great choice for commuting in different conditions. They help you go further, carry more weight without struggle, and can be convenient in low light night/morning conditions if they do have lights.

Popular brands we covered here include:
- Busch & Müller ($40 to $120), can be seen on Riese & Müller products, official website at https://www.bumm.de/en/
- Supernova M99 Pro ($449) can be seen on the Stromer ST2 S and R&M Delite GX Rohloff, official website at https://supernova-lights.com/en/
- Supernova E3 E-Bike V6s ($149) can be seen on many Riese & Müller models, official website at https://supernova-lights.com/en/
- Light & Motion official website at https://www.lightandmotion.com/ at 5:33 in video
- Fuxon has a lot of decent headlights that I've been seeing on BULLS electric bike models, and they do have the side window cutouts. These lights tend to be plastic vs. metal for the more premium products. They alloy does add to your bikes weight and the cost, so it's not necessarily always better.
- Tern has a cool proprietary headlight that fits on their Andros adjustable stem on the Vektron ebike that allows you to physically turn the light on or off. You can see my review of this at https://electricbikereview.com/tern/v...

Most ebike lights are direct current (DC) powered, some dynamo powered lights are alternating current (AC) but it's rare. That said, Chris said that all rear lights are DC and they usually get their power from the headlight as it converts AC to DC and sends it back. I like how some of the newer ebike lights have side windows, so the beam will shine in more directions and keep you visible. I've seen more electric bicycles that now have rear lights that activate whenever the brakes are pulled. This is a European requirement. Chris had some really cool light mounts that help you adapt to handlebars, stems, and the bracket for ebike displays like the Bosch Intuvia. I always aim to mount my headlight up near the stem so it points where you steer and is sprung vs. being down on the suspension arch unsprung and potentially bouncing around. Something I consider when mounting a rear light is that if you place it on the seat post, a loaded cargo rack could block the beam or your long jacket could hang down below the saddle and block the light. Consider the right seat stay, the back of a rack, or your own backpack or helmet for best results. Higher is usually better so cars and trucks can see you. I've seen a couple of ebikes with seat-integrated backlights, and this makes it less easy to swap a rigid post for suspension seat post or different saddle... so it's not my favorite design, it's also very easy to block with a long shirt or jacket.

In closing, many states actually require you to have lights on your bike by law. New York is one such state. Many newer ebikes actually have "always on" daytime running lights (DRL) following automobiles. The LEDs don't use that much energy, and it could save your life, but sometimes it's also annoying, so I appreciate bikes that let you turn them off manually if you want. Usually, ebike shops can show you how to do this or update your software to make it possible (if you've got a Bosch powered ebike especially). Many of the fancier headlights from Germany have a design that aims down, so it won't blind oncoming traffic. EBR was paid to perform this review #Sponsored We try to be honest, thorough, and fun!
