  • Awesome Helmet So Far...👍.
Color: Matte Black Size: XX-Large
I love the fit & feel of this helmet. I really love the visor & no having to wear sunglasses with the visor down. I will say that the helmet could use more air vents, as it get pretty hot in warmer temps here in Southern Kentucky. I also had a minor issue with some of the padded strips inside the helmet wanting to come unglued & roll up on me, causing the hard plastic to come in contact with my bare head, but I fixed that with some superglue & now we're good. I have had the chance to do a night ride yet, so I haven't gotten to test the lights in that situation yet, but every time I power it up at home, they come on very bright & flashing & I've only put one charge to it. The other negative I can list is that the the charge port rubber protective cover doesn't seat well into the charge port, so I'm not sure if it'll provide much protection in a rainy situation. Any way.....I'll still give it 5 stars for now, just because of its functionality, good looks, visor & sturdy feel. ... show more

  • ILM smart bike helmet
Color: Bluetooth Matte Black Size: Large / X-Large
The fit is adjustable as long as you order the size within your measurement range. I like the fact that the speakers cover the ears to keep them warm in cold riding. They sound fine, but are not high fidelity speakers I like the fact that I could answer my phone while riding by merely pushing a button and talking. This helmet is more substantial than your standard bicycle helmet. It is of course rated for E bikes up to 28 miles an hou. Ther strap is adjustable and comfortable. The flip up visor is a very nice convenience in colder weather. I don’t yet know if this helmet would be too warm to wear in the hot weather. It looks like it’s well ventilated so I will have to wait till summer to find that out. The only thing I don’t like about it is the lights won’t come on unless it gets dark, but I didn’t buy it for the lights. I may be wrong about their functionality, but that’s what the instructions say. Ride safe. ... show more

  • Fits nicely and comfortable.
Color: Bluetooth Matte Black Size: XX-Large
Great helmet, comfortable and tough. Great lighting and the automatic braking light and turn signals work great and Bluetooth ability is a plus as well… All in all a good helmet… I wouldn’t use it though if you’re traveling faster than 28mph. I believe that’s what it’s rated for,,, Safety first…

  • Extremely high quality at an excellent price point
Color: Bluetooth Matte Black Size: Small/Medium
I bought this for my daughter to use with her new ebike. She loves it!! The Bluetooth feature is indispensable. She can hear everything around her but can also hear her GPS right in her helmet. I also love the safety aspects of the light on the back and lightweight face shield. It looks absolutely amazing on her and fits like a glove. My only complaint is with the face shield not wanting to stay in the up position after she had used it for a few days. That's not a huge deal for her because she uses it down anyway. This is an extremely high quality product that performed way beyond my expectations, even with the sun visor issue. I would totally recommend this to anyone who needs a good lightweight helmet with lots of tech. ... show more

  • Great quality product
Color: Matte Black Size: Large / X-Large
Super awesome product I only wish I didn’t look like a special ed kid with it on. (Not trying to offend anyone it’s just how I felt for myself) Super light weight great quality materials. It did feel like it protected my head very well. The eye shield was great to help protect my eyes during the day and it’s also removable. It was super easy to removed and install the shield on and off. 10/10 recommend ... show more

  • Concerns Over Fit, Adjustment & Safety.
I generally hate to give negative reviews, but maybe this will help fix this issue. I purchased this helmet because I thought it had a high safety rating. It also appeared to have better head coverage than other helmets. But...... The adjuster that adjusts the head diameter for this helmet is very flimsy. I noticed as I tightened it, it started to slip. After more experimentation, I found that no matter where I set the tension, any pressure would cause the adjustment to slip open and make the helmet extremely loose on the head. This could be catastrophic in an actual crash and possibly cause the helmet to slide out of position or even off the head. In addition, this helmet when tightened properly had excess propensity to rotate back and forth compared to other helmets I have used. If this helmet stayed on your head, it may be very safe in a crash, but I think this helmet may not stay on your head if any pressure were applied to it. At best, it may stay on but not be positioned properly during a crash. I have no confidence in this helmet. Maybe the mechanism on the one I receive is just broken/defective but compared to other helmets the head adjustment band seems very flimsy to me. ... show more
