Have they taken the product apart and inspected everything for quality assurance then reassembled have they??? Of course not!!!!, I make sure the battery is top quality, the charger actually shuts off when fully charged so you don't have a fire!!!(Very Important)  I stand behind all of the products I sell, I'm not just a seller but an avid rider, you may be able to find it cheaper somewhere else but chances are that cheaper unit your buying will not come with after sales service and most likely the seller doesn't know anything about them aside from the fact that they're round and shiny....lol.  Don't want to wait for overseas shipping, I have these units in my possession will ship within 2 days.... Get it fast!!! Between 1-7days from the ship date!!  This Gotway Brand wheel is the best wheel available and if you're looking at this ad, chances are you know exactly what your looking for, so look no further, you have found someone who will take care of you AFTER THE SALE!!  I've been riding these things for a while now and I'm in love  with this sport so much that I'm now selling and servicing these locally where I live. I've also  started a group ride session once a month where we all get together and just  cruise.....it's such a rewarding experience, I get to meet tons of people who  always ask, what the hell are you riding??.....lol, then I pass them a business  card and set up a try before you buy session, and viola, they're hooked!! You  will not find a more fun way to commute to work or school, you  just might be late though because of the constant questions and people pulling over to stop and ask you what it is, not to mention the thumbs up as motorists drive by you while you cruise:), yeah it's one of the easiest ways to get into the sport  out there I sell these locally, and it usually takes my clients about 30 min to learn how to ride a few feet........... about a week to really get  comfortable.....then fun, fun, fun. Works just like a Segway, lean forward a  little, move forward a little,  lean forward a lot, move forward a lot. Lean back slightly to slow down and you got it.  I accept all major credit cards.....this is a real business for me and I treat it like one, yes we will take care of any concern you may have.  I'm selling these locally also so inventory is subject to change but I have 5 of these beasts!!!  Black Carbon Gotway M super 680wh Larger battery capacities available also I can get any model of wheel you might need, just ask as I have an exclusive relationship with one of the largest suppliers dedicated to this amazing industry.  This unit will ship for free!! yes that's right free shipping, considering this box is over 55lbs that's a deal trust me.  We are located In Brentwood Ca, 94513 in the USA  Item specifications: Max Speed: High speed style 42+MAX this listing is for the medium top speed configuration, but we carry all of the speed configurations low,middle and top!
