The complete integration of the Optibike is achieved from the ground up with a disign focused on high performance, safety, and ease of operation. Front and rear long travel suspension with disc brakes gives the rider confidence. The fully integrated package gives the utmost in convenience allowing the rider to ride on road, off road and the up or down the steepest hills. Optibike is in a class of its own. The Monocoque frame has sleek styling and a low center of gravity for stable handling. All electronics and long-running battery are safely housed inside the frame.
Propel started in a small, second floor office with a motivating belief that electric bikes would change people’s lives, and they have. Since 2011, we have been closely listening to our customer’s needs, spent countless hours traveling and researching to learn more about ebike technology as it evolves, and we are advocating for changes in policy that promote a more equitable stake for electric bicycles in the world of transportation. Join us in this movement towards a more sustainable future; together, let’s change the way we move.
The bike recently took first place at the Interbike Hill Climb Challenge, a third of a mile sprint up a six per cent gradient hill. Fortune powered in front of professional riders to secure a decisive win in the first of an annual competition especially created for electric assist bikes. The race was sponsored by the Light Electric Vehicle Association (LEVA).
Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.

The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
Propel is a Brooklyn based electric bike shop serving NYC and beyond. We work with many electric bicycle brands including Felt, Specialized, Easy Motion, Cannondale, Riese & Müller, Stromer, Bulls, Haibike, Focus, Kalkoff, Moustache, Xtracycle and more. We carry many types of including fast electric bikes, electric cargo bikes, electric folding bikes and electric mountain bikes. Feel free to reach out if you have any questions about ebikes we’re excited to help this movement grow.
One of the biggest misconceptions about e-bikes is that you're not actually doing any work when you ride one. Not true. Thanks to that battery-powered motor, E-bikes are heavy! So if you turn the assist mode to low or off, you're still putting in plenty of effort. Many commuters have found that traveling home from work with assist off (when they're not in as big of a rush and don't mind getting sweaty) is a great way to fit exercise into a busy schedule.
Both Vintage Electric and Optibike build more expensive electric bicycles in smaller numbers that are geared towards wealthier clientele. By focusing on what some would consider “luxury electric bicycles”, these companies might be better positioned to either absorb the cost of increased tariffs on imported parts such as electric bicycle motors, or find customers with enough expendable income that the higher prices of the final e-bikes wouldn’t be as large of a deterrent.
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
