Concept Bicycle Helmet That Tucks Into A Water Bottle – UPDATED

UPDATE 2/21/2020: Following up on the much-hyped Park & Diamond foldable bicycle helmet, it appears the company has not yet delivered a single helmet. The company’s last update to their 13,040 backers explains that the latest delivery delay is due to…wait for it…the Coronavirus! This is six months after the company claimed that a production “bottleneck” had been resolved to assure a higher production rate and faster delivery. I can’t find verification that the helmet meets or exceeds the U.S. CPSC cycling helmet standard. I suppose the company could get…

Jeep E-Bike To Debut In June

There has been a lot of hoopla surrounding the Jeep e-Bike (that’s its official name so far) since Bill Murray introduced it during a Super Bowl TV commercial (not something you expect to see from bicycle or E-bike companies). The bike is to be released in June and I assume it will be sold through Jeep dealerships as an accessory item to a Jeep purchase. It may be used as a buying incentive. Who will service the e-Bike after delivery? Probably your local independent bicycle shop. The announcement is a…

Modified E-Bike’s Fiery Explosion A Warning

An E-bike with a modified battery ignited into flames that were quickly contained because of the fire’s close proximity to an extinguisher. Reports were not clear if the bike was privately owned or used by a food-delivery service. The Straits Times reports that the fire took place in Singapore where, unlike in the United States, there are strict laws on e-bike modifications (that obviously didn’t deter this owner from making modifications) and there are a much larger number of E-bikes in operation than in the States. As E-bike use expands…

Updated 1/15/20 – Battery Fires Create Concerns For Every Electric Bike Owner

Bike Europe, a publication claimed to be the “leading trade journal for the bicycle, e-bike market” recently published a courageous story on the dangers of Lithium-Ion batteries used in the majority of electric bikes (e-bikes). The publication had a fire safety engineer and battery safety professional examine the aftermath of a fire ignited by an unattended charging battery in a bicycle shop (click here to watch the ignition and blast-off). His observations are frightening. The expert is quoted as saying that Lithium-Ion batteries are, “rather unreliable, rather explosive. You are…

30-Mile-Per-Hour Scooter Scares The Crap Out Of Me

When I worked for Bell Helmets during the 80’s, one of the Company’s largest concerns was product liability. It wasn’t because Bell was making a sub-par product. Quite the contrary. Bell was rightfully respected as the finest helmet company in the world. The testing lab was amazing and the quality control second to none. There were racers sponsored by other helmet companies who would buy Bell helmets, remove the stickers and replace them with their sponsor’s sticker (I am not making this stuff up and saw it first hand). But…

Jimmy Mac On Two Wheels’ Most-Viewed Stories of 2019

I’m not sure why the top stories of 2019 are very important. I don’t have advertisers to appease and I don’t monetize my loyal readers. It is not a fair measurement because the stories posted in the first part of the year had more opportunity to build an audience than the stories from a month ago. I guess I’m just curious what stories spiked the status quo and if you missed them, you get another shot to read them. So here you go. The most-read stories of 2019. E-Bikes Not…

Cheaper, Faster, Off-Road E-Bikes Threaten Multi-User Trail Networks

I lamented that the Suru Scrambler represented everything wrong with allowing electric-motorized bicycles on multi-user, natural-surface trails. Less than a year later, the E-bikes headed down the trail make the Suru look quaint in comparison. The E-Cell Super Monarch AWD 1000 is a perfect example of an E-bike that is blurring the line between E-bikes and motorcycles. The E-Cell Super Monarch AWD 1000 (AWD stands for All Wheel Drive) was recently reviewed by the website Electrek. Their test states, “While the bike does come factory limited to 20 mph, it’s…

Antagonizing Motorists Does Not Improve Rider Safety

I’ve noticed a number of well-meaning experts touting the use of pool noodles by cyclists to keep motorists from passing too closely. I believe this is bad advice that may be counter productive and potentially dangerous. Here’s why. Years ago I was given a jersey that read “3 Feet To Pass” and had graphics of a big arrow and an automobile passing a cyclist. I thought it was pretty cool. My first ride in it dampened that enthusiasm. It seemed like an inordinate number of vehicles passed dangerously close (by…

The Major Flaw in Brigham Young University’s E-Bike Paper Revealed

A flood of headlines last week appeared to be clickbait because of their preposterous claims. The articles from Outside, The Verge, Men’s Health, KSL.com, Adventure Journal and Electrek referenced a study from Brigham Young University claiming that riding an E-bike requires close to the same amount of energy as riding a bicycle. Anyone who has had the pleasure of riding an E-bike knows the main attraction of electric-motorized bikes is how much they reduce the energy needed to ride. These media outlets were claiming the study proved this perception wrong.…
