I purchased the E8 Searcher and it has a 24v, 10ah stock battery with the 250w front hub motor. What can I do to make it a better E-Bike? By this I mean the motor barely has enough power to climb hills in this area and the Battery only lasts for approx 3.5 miles of the hills. I assume everything would have to be replaced but keep in mind I would like to be able to go 20 miles minimum at approx 25 MPH, and still have some power in reserve. I am a 230lb 6'1 rider. I believe the Schwinn frame weights in around 40 Lbs. Thanks for any help/suggestions
 
Welcome to the forum. Its hard to make a good recomendation without knowing more about your hills and riding conditions, but a basic setup capable of 20 miles range, with comfortable reserve at 25mph would need a 700 watt hour battery, a 500 watt motor, and very likely with your weight, a 30 amp controller would be best


An example would be a 500 watt Nine continents 2807 motor with a 48 volt 15 Amp hour Lithium based battery and 30 amp controller. Thats capable of 27-29mph peak speed and 1500 watts peak output, so good for cruising at 25mph. But there are many ways to achieve the same thing.
 
Didn't see any 30a controllers. Did have someone recommend a ?computer? by Infineon. Battery ratings that I read about by the numbers don't seem to have more than the stock battery. Should the bike be switched to a rear motor or stay with a front motor? Is there a all around really good kit that comes with everything as you suggest?
 
Schwinn has discontinued their E-Bikes. I took mine for a ride and it did okay stock. I extra battery in my side bag would make all the difference. When I called to inquire about a battery, I found out the Bikes are discontinued.
