The G-10 features a top-tube mounted on-off button and ‘set’ button for one of four power modes, all linked to a Groove Go wheel mounted motor via a removable clip-lock battery stashed under the down-tube. Kalkhoff has paired this with a mid-range Shimano Tiagra 1x10 speed drive-train and effective Shimano M396 hydraulic disc brakes. A nice touch is the anti-slip ‘grip-tape’-covered flat pedals, perfect for a bike to be ridden around town without specialist shoes.

We are making room for all the new models of Pedego electric bikes soon to arrive. Owners Jean & Terry of Pedego Denver electric bikes have always had the largest electric bike store in Colorado along with the largest selection of Pedego Bike models & colors. So with the unveiling of several new models & colors at the recent Pedego Dealer Conference in Newport Beach, CA. We realized that we needed more room to display them, so we decided to expand and even moved walls to do so. We now have over 5,000 square feet making Pedego Denver one of the largest showrooms in the nation and a true Mega Showroom. The new space also includes a new Pedego experience...
The Panasonic Akku cells used in this pack are among the best lithium polymer cells Panasonic makes, which is one of the finest names in the industry for lithium battery technology. This means the pack will give you years of long life without worries about a battery fire or breaking down. The battery, along with the rest of the components of this electric bike, come with a 2-year warranty. The bike comes with a relatively fast 200-watt charger that will refill this pack in only 2.5 hours. And the battery locks into the bike with a key lock, good for preventing theft. The battery pack includes a built in battery meter that shows battery level whether it’s on or off the bike.

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.
Designed for urban or suburban commutes, the A2B Octave (right picture) offers lightweight aluminum construction with full suspension. Add in its comfortable,oversized seat and you have a powerful ride that's easy to handle. When you don't feel like pedaling, the A2B offers unassisted power on demand for up to 20 miles at a cruising speed of 20mph. Plus, the A2B can be easily upgraded to double its range to 40 miles with the addition of a secondary battery pack and increase its carrying capacity with the addition of baskets and rear carrier bags.
The Ancheer Power Plus can be ridden in pedal-assist mode or fully electric. The removable battery can be charged on or off the frame in 4-6 hours and you’ll get up to 31 miles from a single charge (15 miles if you don’t want to pedal). It’s a great bike for short commutes and light off-roading, though if you’re tall, you may find the one-size-fits-all approach doesn’t fit you.
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.
