1000 Watt Rear Wheel Conversion Kit $260.00
or if you want name brand then
Magic Pie
Hub Motor Kit Magic Pie V4 Complete Kit E Bike Conversion EBike Kit 1500W 30MPH | eBay
Bicycle - $300.00 Take your choice
Then find a bike mechanic and pay $200.00 -$300.00 for assembly
Total Cost- $1300.00 -$1500.00 or if you are handy then deduct the $300.00 for labor, and this bike will KA almost all the premade bikes. Around 28mph - 30mph no pedaling.
Obviously you have never used long term a good 3k crank mounted system....
Ok one of the main advantages to the crank located motor is it gets to use the bicycle gearing, like the rider does. Electric motors have a fairly narrow rpm power band like humans. Also just starting the motor from zero rpm takes a lot of power. Getting the rider to start the movement is a huge battery energy saving. If you ride a hub model and go to crank power you will be amazed at the benefits.
If you are just out for speed that is one thing, if you want a quality piece of equipment that will last and work well that is a totally different story.
