Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
Unfortunately, not even this great bike is perfect. The otherwise great performance is somewhat let down by the weak disc brakes. Stopping time could be improved with an upgrade. The relatively high weight of 59 lbs is also a disadvantage, and lots of the weight is on the rear wheel, making the GB5 500 prone to accidental wheelies if you accelerate too hard in throttle mode.
Obviously, you shouldn’t ignore traffic rules and try to weave around cars – that’s dangerous, even for unpowered bicycles. However, folding electric bikes can fit places that cars can’t – alleyways, or even sidewalks – though again, you should follow all posted laws and regulations about where to ride them. Using your surroundings smartly in an urban environment can help you avoid traffic completely.
Moulton - this rugged British bike with a full suspension appears to be designed to compete with full-size bikes and win - the Moulton holds the world speed record for bicycles of conventional riding position at 51 MPH. The Moulton's unconventional cruciform "separable, not folding" frame is made of a lattice of small diameter tubes that make the bike light yet stiff and efficient. Its small high-pressure tires actually perform better than full-size tires in a variety of ways. The newest versions also offer a fully adjustable handlebar that allows the bike to adapt to urban, touring, and racing uses. The more you learn about this bike, the more it seems to be designed not so much to travel compactly (which it is) but actually to be superior in design, performance, and versatility to a standard frame bike. A typical Moulton weighs about 22 pounds and separates to take up about as much space as other small folding bikes, although folding time/size is not touted for this brand. Prices range from under $1500 up to $8000. www.moultonbicycles.co.uk.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
My husband and I purchased a Vika + each. We have hip problems and I can't walk for any distance. But I CAN ride my new bike. I LOVE it. My husband had a hip replacement and wasn't riding very much anymore because of the hills. Now he has no problems with them and is really enjoying getting out riding again. I get around 34 miles to a charge and he gets double the mileage I get. When we ride I always have a smile on my face!!
Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres. Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.
A big selling point of the attractive Citizen Bike Seoul, sold direct from the company’s website, is that it comes straight out of the box ready to ride—on our test unit, even the tires were inflated. Unfortunately, we didn’t find the ride and gearing as smooth as those of bikes costing just $100 more. Though the folding and unfolding were easy, the magnets simply wouldn’t hold when the bike was folded, and it kept flopping open (especially problematic when I was carrying it down subway stairs); the company told me that an update on that was coming. Plus, the Seoul’s folded footprint was so large it wouldn’t fit through the subway turnstiles.
In the event that you're going to be living somewhere for an abbreviated period of time, a folding bike might be a smarter choice than a car, as long as your daily commute isn't too far. For many city dwellers, there is simply no place to park a car where they don't have to worry about getting a parking ticket on random days. A folding bike is ideal if you're living in a dorm room or a temporary apartment. Another benefits besides the low upfront cost, is the tremendous resale value many have, which means that you can recoup a lot of the bike's original cost when it's time to sell.
I unboxed, assembled (if needed), adjusted, and assessed each bike for my initial impressions, taking them all on a short first ride around my neighborhood in Queens. In a few cases, the bikes needed more extensive adjustments, for which I brought them to Nomad Cycle in Astoria; if you buy a bike online, you should bring it to a mechanic for a once-over, no matter what.
It’s hard to tell anyone to spend more money. But seriously—if you’re looking for a folding electric bike that can reliably replace your car, then it might be worth it to save up for a sturdier e-bike that can schlep just a little more. If you’re actually looking for a fun toy to get you from the subway to work without breaking a sweat, Jetson’s own Bolt is both lighter and cheaper, leaving the poor Metro between a rock and a hard place.
Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.
