Diamondback Alliance 1 review: commuter electric bikes that might make you give up your car


I have found There are many reasons to embrace the new city-friendly type of Rattlesnake Alliance 1 Electric bicycles this summer, record-breaking heat and months of wildfire smoke made other forms of cycling less fun. Coupled with the excessive road construction and rising gasoline prices in my city, running errands has become an oven nightmare. The salvation grace is Union 1. This is an electric bike that brings joy, speed and style to cross-city trips-especially those that end on the beach.

Diamondback is known for its “acoustic” gravel and mountain bikes, and is a newcomer to the growing e-bike segment, but its parent brand, Alta Bicycle Group, It also has Izp, Raleigh with Hybick,no. Alta’s institutional electric bicycle history means that Diamondback does not have to reinvent the wheel (or motor) before launching four electric bicycle models this year. This is a mid-priced urban warrior series, each offering high-performance components, a robust structure and Exquisite grade.

Union 1 is equipped with integrated fenders and rear luggage rack.

Among the four, Union 1 with aluminum frame has the lowest cost, but it is still impressive.It was built around Bosch Performance line speed The electric motor is equipped with an 85 Newton-meter drive that helps the rider reach higher speeds and cover longer distances-35 to 55 miles per charge, depending on the pedal assist level you dial in. Was rated as level 3 For electric bicycles, Union 1 has a maximum speed of 28 mph, which is the maximum speed allowed by electric bicycles in the United States. The motor is powered by a 400 watt-hour battery, which is fully integrated into the down tube, reducing the overall volume. 10 speed Shimano The drivetrain can be easily shifted, and the hydraulic disc brakes (as my bike shop mechanic pointed out after a trial run nearby) are powerful enough to really stop this 51-pound machine very quickly, while the electric bike This is not always the case. The simple, simple Bosch Purion computer display on the left handlebar displays large numbers on a black and white LCD screen, making it easy to read. The sturdy 27.5-inch wheels have tires suspended from them. The tires have a city tread that is strong enough to handle even dilapidated asphalt and roads. The integrated bike rack and mudguard can place luggage on the bike and prevent cyclists from getting dirt.

The best part of Union 1 is the smooth, seamless ride. Like most Bosch powered electric bicycles, the motor provides four modes: Eco, Tour, Sport and Turbo. Add 10 gears to the drivetrain, and your choices range from uphill exercises that are almost impossible in Eco mode to easy pedaling in Turbo mode reminiscent of the launch of a rocket ship.

When riding an electric bike, I don’t care much about sports, but more interested in fun, which means that as long as the battery is charged, I tend to keep the bike in Turbo mode. During my last 12-mile ride, after stopping and jumping off the bike and jumping into Lake Superior to cool down, I needed to climb 1,200 feet on the gravel road. What impressed me was that even when I was driving, I was only It consumes 40% of the battery power to keep the bicycle in Turbo state. On long-distance rides within 20 to 30 miles, I switch it back to the more conservative Tour or Sport mode, but the battery power rarely drops to dangerously low levels. The ultra-conservative Eco mode is perfect for those who want to really exercise or can ride more than 35 miles on a single charge, but I found that the force of stepping on Union 1 in Eco sprained my knee, especially when going uphill.For more details on the bike reference range in each mode, please refer to the handy of the rattlesnake Range calculator.
