The Pedal Assist System, or PAS, is a feature of your e-bike that provides extra power behind each pedal. It all runs through the LCD display located on the handlebars, from here you can toggle between one of 7 levels of assistance and turn on the PAS. Once you turn it on, the system engages each time you pedal on the electric bike. If you don’t press the power button to turn on the PAS, it will feel like you’re riding a regular bike when you pedal. I always thought electric bikes let you pedal at you own speed with the motor helping out. The Marshall looks like a mountain bike with a comfy cruiser feel to it. A step-thru version offers a slightly lower top bar than the regular version. Upway offers you to select if you would like to receive your bike either 85% assembled or 99% assembled. It’s basically the Goldilocks option, offering enough performance and functionality for everyday commuters without pushing the price too high. If you leave the battery in the bike, there is a rubber port cover you need to move before plugging in the bike. This helps keep the battery dry if you get caught out in the rain. Some of the added weight is attributed to the battery, which checks in at about six pounds. There are five speeds you can adjust via the bike's thumb pad controller located on the left handle. The LED display shows you how much assistance you're getting, as well as how much battery life is left. When you want to stop, just squeeze the brake levers and the motor cuts off. The Schwinn Monroe 250 gets its 250 moniker from how many watts the hub drive puts out. A tough, well-balanced, affordably priced, single-speed electric bike from a well established brand, available in three frame sizes for improved fit, sporty forward-leaning geometry. No suspension elements but the fork is steel which provides some vibration dampening properties and…... The standard batteries that come on our Marshall, Coston CE and Coston DX bikes are good for up to 45 miles of riding. But Schwinn knows many riders want to go farther, so we developed higher capacity batteries that are super easy to install (you'll only need a screwdriver). These additional batteries extend the riding distance up to 80 miles on both our Coston and Marshall series of bikes. One of the valid concerns raised by riders of e-bikes is the ability of their e-bikes to hold a charge and provide pedal assistance when they're out for rides of longer distances. One thing I miss from previous e-bikes I've had was a range estimator that gave you an idea as to how much further you could ride at your present power level under present conditions. Such a feature is fairly inaccurate all things considered, but some estimate is better than no estimate. In the United States, however, bike companies had to find bike buyers outside the mass market dominated by bikes made in Asia. American and European makers geared their bikes for competitive riders, such as triathletes and other road racers. Unbeknownst to me, the company has a line of electric bikes designed for entry-level cyclists. If you are in the market for an electric bicycle, I personally recommend the Lectric XP Lite. It’s necessary to clarify what it is you want the bike to do. Fat tire bikes are all the rage, but the noise those big wide tires make is a deal breaker for me. There are very sophisticated e-bikes that have the motor integrated into the crankset. That is ideal for keeping the weight of the motor low and centered within the frame, but those machines can cost big bucks. I had already decided I wanted one, so I said I would take the gray one. Despite my weight and the strain it put on the motor, I found that the bike really does have a 45-mile range on a single charge. I didn't have a chance to precisely time how long the battery takes to charge from empty but it recharged completely overnight or during a full workday. When I pedaled hard, the bike was able to get up to 20 mph in about 10 seconds on smooth, flat surfaces. Pedaling uphill was a bit different, maxing out at roughly 15 mph. Lighter people may be able to get it going a bit faster, though (I weigh 250 pounds for context).
