Though aside from the extra battery and abundance of included accessories, Riese and Muller’s use of a Gate’s belt drive means no shifting of gears, no greasy maintenance, and much higher durability. If you have the money to spend, Riese and Muller’s Delite nuvinci is one of the best on the market and an ebike we just couldn’t get enough of during our own tests.

Kalkhoff enjoys an enviable reputation by virtue of a long and revered history based upon obsessive craftsmanship and insistence upon only the most indestructible and ecologically attuned processes, materials and components, together with the most stunning and intuitive technologies available. Their bikes are over-engineered to over-perform and yet stubbornly maintain value over time.
Using an electric bike for long-distance touring has its pros and cons. The motor will help carry the extra weight of your kit, particularly on the hills, but you have the added hassle of having to charge the battery every night. You’ll want a powerful motor and a good battery, though if you’re fully loaded, don’t expect to achieve the maximum advertised range.

Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
“Yamaha e-Bikes are in shops, and we’re hearing some great feedback from our first retailers and customers, coast-to-coast, from California to Maryland. From casual commuters to series cyclists, more people are seeing the advantages of incorporating an e-Bike into their daily lives. Yamaha has been the global leader in Power Assist Bicycle manufacturing for more than two decades, and it’s exciting to now rollout the first ever Yamaha e-Bikes in the U.S.”

A representative for another large international bicycle company informed me that his company is now shifting its production of their 2019 electric bicycle models to two other Southeast Asian countries to avoid the import tariffs on Chinese e-bikes. The source spoke on condition of anonymity as he was not authorized to speak publicly on the matter.
Because they’re electrically powered, e-bikes sit in a bit of a gray area between bicycles and motorcycles. While some states have enacted specific legislation to state where electric bikes can and can’t be ridden, in other states outdated laws mean they’re regulated as a moped or motor vehicle which can cause confusion over registration requirements, access to cycling infrastructure and how old you have to be before you can ride one.

Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.
