I built an Ebike from a rear wheel kit back over 5 years ago. It used(still uses!) a 300 watt 36v motor. At the time I purchased a 20ah battery pack for it(which still works fine) and later used four 36v 7.5ah scooter packs that I got cheap from Ebay to make two, 36v 15ah packs for it. That bike served me fairly well until recently when I began to crave the better hill climbing torque offered by newer, more powerful, more advanced Ebikes. I also wanted better range and much less battery charge anxiety. I wanted an Ebike that felt more useful than novelty. I guess what I really wanted was an electric moped. Which I pretty much found in the Aniioki AQ177 pro max. The AQ177 has the largest single battery pack Ive seen on an Ebike giving it well over a 100mile range for someone in my "lighter" weight catagory. There was another, very similar ebike that I considered called the Juliet that also used a 60ah battery pack but that cost $300 more and, at least to me, didnt offer anything more for the extra money. My AQ177 was delivered last Wendsday and Ive put about 200 miles on it so far. Also, so far, Ive yet to make a dent in the battery bar gauge, even after tooling around both towns I live between doing errands all day. Loving this AQ177-again, so far! I did get a flat the other day, but that is normal happening for any ebike. I use to get them a lot on my old ebike too-until I put one of those PVC liners in both tires. For mods on my new ebike, I added a few but dont plan to go crazy. I transferred a large capacity rear basket from my old ebike to the new because thats where my dog rides and she goes everywhere with me. I also added a smaller basket to the front for groceries and repositioned the headlight to an accessory bar mounted between the handlebars a little higher up. Ive changed the stock seat out for a seat with a backrest(because Im getting old...er) and finally, Ive replaced the original knobby tires with 60tpi street tires because I spend 97% of my time on tarred or smoothish, hard packed surfaces. In my opinion the 180mm, hydrolic disc brakes the bike comes with are very adequate so dont need messing with. Neither does the front or rear shocks need upgrading-again, in my opinion. Ive read posts from guys who say they weigh nearly 300lbs and then complain that the stock shocks on their Ebikes bottom out. Well, yeah??? Why would they expect differently? Oh yes! I also added a mirror to my left handlebar so that Ill be able to see the approach of the car that ends up squishing me!. Anyway, thats my story and Im sticking to it. Im a long time ebike rider but no expert. Loving my new AQ177 though. So far....!
