Although e-bikes were invented in the 1890s, they've exploded in both demand and variety since then. So many exist that it's just a matter of figuring out which one best fits your needs. For people with limited space, folding e-bikes might be ideal, and some of them are astonishingly versatile. For instance, the Enzo Folding Aluminum is fairly high-performance, able to go up to 50 miles and carry up to 275 lbs. Its frame glows in the dark, and it comes with a bell, rear rack, and storage bag. The admittedly weird-looking Pacific Cycles Carryme Dc folds lengthwise, weighs a mere 28 lbs., and is height-adjustable. The super-cool Gocycle G3 can travel up to 50 miles at speeds of 20 mph and has interchangeable wheels.
The Mariner 7 Folding E-bike from Prodeco Technologies, a US-based manufacturer, is about the same weight as the Enzo. Its 300-watt motor is a front-mounted, geared hub type, and the removable battery pack consists of a 38.4-volt, 24-cell lithium iron phosphate. The mid-step, folding frame, handlebar, and folding stem are aluminum or aluminum alloy, resistant to rust and salt-watery air. The Mariner 7 features an SRAM X5 8-speed derailleur, SRAM X7 grip-twist shifting, and Avid BB5 mechanical disc brakes. Its range is a decent 25 to 35 miles with a top speed of 18 mph. The LED console shows battery level, and charge time for the bike is 4 hours.
Options for the Mariner 7 include an adjustable kickstand, a 43.8-volt/ 2-amp charger, an aluminum bash guard, and a bell. While this e-bike is praised for its affordability, shock absorption, torque, and braking, it is criticized for its heavy battery and the battery position, the too-soft pedals, the want of fasteners for keeping it folded, lack of rear storage capability -- because of battery pack placement -- and lack of mounts for panniers. So, this bike is a great deal for college students living near or commuting from beach communities.
The bicycle is very well built from both an aesthetic and engineering perspective and works superbly. I purchased 2 bikes and am very happy with both of them.
I purchased two. Used both for 2 months. Next summer, one motor not functioning properly. Dropped off for repair. Craziest service I've ever experienced!
The ride quality of the Mariner 7 is acceptable. The pedals are plastic and therefore not that stiff. The weight of the battery is elevated high off the ground...
Though not the best product in its category, the Mariner 7 is worth a shot especially if you are limited by budget.
