There is a whole thread on e-bikes.
Here is a link to one I contributed to....
Are more people on this forum getting e-bikes?
I love e-bikes. You will see from my post in the other forum I use it as my main form of transport in my town to get around.
Aventon is a great bike at a good price. I paid $1,705 US which includes a military discount of about 5%.
I also got an extra battery at $250.00 (normally $500). I keep one battery always charged as I wear down the one in the bike. I go out for about 45 minutes 4-6 times before it gets below 20% and I put it on the charger.
The most important thing is the quality of the battery. Never get one directly from China or a questionable source. Always get it through the manufacture and only if they conform to UAL standards. Never charge overnight or when you are away from home. Just a precaution I take.
Duel drive? Not needed. Single drive is the only one you actually need. It goes about 25 mph, but you can modify through settings to get to 30 mph, but, who needs to go that fast?
Don't go with a kit to modify a regular bike. Very unsafe. 1) a regular bike is not set up for speed of an ebike. 2) the breaking system needs to be disk brakes, front and back, 3) The frame of an ebike is much stronger, 4) you would probably get a less than quality battery.
They are heavy with the battery in, so hopefully storage is not climbing up and down stairs.
I have no problems with the Aventon. The shipping is quick and it comes with easy to assemble instructions (about 30 minutes to put together).
I got seperate insurance made for ebikes. covered against loss, theft, accidents, etc. $11 a month.
Good luck! You will love an e-bike....8,000 is alot for an ebike. Aventon is much less expensive and the quality is great.
The best purchase I made since retiring.
Get a good lock. If you go with the insurance, you need to buy a lock approved by the insurance company. not a big deal though.
