At the close of the 1920s, the stock market crash decimated the American motorcycle industry, taking Excelsior-Henderson with it. Arnold, Schwinn, & Co. (as it remained until 1967) was on the verge of bankruptcy. With no buyers, Excelsior-Henderson motorcycles were discontinued in 1931.[5] Ignaz's son, Frank W. W. Schwinn returned to Chicago and in 1933 introduced the Schwinn B-10E Motorbike, actually a youth's bicycle designed to imitate a motorcycle. It features a 7-speed twist shifter that offers smooth gear changes paired with mechanical disc brakes for stopping power in all weather types. Its battery also has integrated LED lights on either side, as well as both head and taillights so that you’ll be seen in low-to-no-light rides. A growing number of US teens and young adults were purchasing imported European sport racing or sport touring bicycles, many fitted with multiple derailleur-shifted gears. Schwinn decided to meet the challenge by developing two lines of sport or road 'racer' bicycles. One was already in the catalog — the limited production Paramount series. The Paramount series had limited production numbers, making vintage examples quite rare today. Plus, our hands-on time with it leads us to believe it's strong and durable enough to use for commuting. Rest assured, riding one of Schwinn’s e-bikes will quickly feel just as second nature as riding the traditional (or analog) bike you’re used to. In fact, we’re pretty sure you’ll end up preferring it to your old bicycle. The new Swytch GO is simple, easy to install, and cost effective to manufacture… Without compromising on reliability and safety. But even the mid- to low-end Shimano parts are perfectly fine for this level of bike. Like all of our buying guides, our advice is gained through countless hours of using products in the real world, often back to back against their peers to compare them, but ebike conversion kits have an additional need. There are plenty of reasons to install an electric bike conversion kit to your current bike, but the question of whether it's worth doing is going to depend on your circumstances. Consumers have a tendency to look away when they encounter a new brand. It's not a bad strategy most of the time but in the electric bike world, including conversion kits, you've got to be more open than that. If you aren't open to names you've never heard of you will find the options limited. A lot of the names you may come across will be unfamiliar to you but have a solid history behind them.
