Question: big enough for small woman? Stingray 20in. bike...  I am a very short woman 5ft.2... I assume that I could use this bike?? the other electric bikes have all been too big for me.  I.
Document: I usually use the electric as more of a boost, so that my legs do some of the work. I've ridden it on scenic bike trails for over 2 hours without seeing any loss of power or a single bar lost off the power meter. Truly, this is a great bike. I want to alter mine to have more gears, because on a hill it has a max speed of 25mph (I put a speedometer).
Another benefit is that you get to be outside and avoid traffic, meet other bike commuters and spend an hour or so geting in touch with nature. It is a win win situation, the environment benefits and you could improve your health.Schwinn 20" Stingray 250-watt Electric Bike S2938
The electric bicycle is a great alternative to gasoline driven vehicles. An overnight charge gives you a speed of 20 mph and a distance of 20 miles and the cost is about 25 cents of electricity. If you just use it for neighborhood errands, like a run to the store for bread and milk, it could save as much as $6,000.00 a year.
My whole experience with the Schwinn S2938 electric bike has been great. VM Innovations (via Amazon.com) delivered it in 3 days at a price of $[...] plus $[...] S&H, which was $[...] under listed costs from other providers for the same bike. Most electric bikes were pricing out at $[...] so I expected it to be somehow deficient.
Cons:Very Heavy (100 lbs),feels like a small motorcycle, so return shipping would be really troublesome!In storage for long time, so batteries might arrive deadNO SPARE PARTS availablePros:Looks goodFast shippingAlso, this is not a bicycle as some have suggested. If the electric power doesn't work, you can't paddle it for long. Be aware!I ordered the bicycle after reading the reviews here. Bike arrived on time but assembly was problematic unlike some have said.
15 mph equals 22 foot per second and fast enough to really get hurt.I called every bike shop in the Oklahoma City yellow pages with no luck finding an electric bike. Finally found a bike shop 64 miles away that offered to put a $1500 motor kit on a new $250 bike for me.My advice...bookmark this page then shop/call around till you give up then come back here and order one for yourself.
I bought this bike to commute to work. I ride 10 miles to work, then charge it at work (just to be on the safe side). It is hard to pedal without any electric power, so don't get caught without it. It is very sturdy and I have no doubt it could hold 300 pounds, although I doubt it recommends it (I don't have the manual with me at this moment).
I haven't fully tested it's full range, but 10 miles only takes 2-3 hours to recharge so it has spare capacity. Its speed is somewhere between 15-20 mph (haven't actually measured it). It's somewhat torque limited so I pedal a slight amount to go up hills and to get started initially, though it could tough it out on it's own at a slower speed. I highly recommend it to everyone.
The bike is loads of fun (even for an older person!!!) just enough speed without being too fast... Everyone in the neighborhood wanted to try it... including 60 year old men!!! (all under the 200 lb.
My husband loves this bike-it is the talk of the town (small town). This bike allows him to get around (He has PAD). He liked it so well he bought one for me also. We have two and love them. It is everything the advertisment stated and more. It will go at LEAST 14 miles on one charge and probably farther. Quiet--and we do not have to license it in our state.
