I noticed there are no comments posted more recent than 2017. Be aware there has been a recent change of ownership in the entity who distributes the Haibike brand in the US. My experience is with the new entity who it appears distributes numerous brands of bikes in the US. I bought a 2018 Haibike 8.0 All Mountain X Duro last year in SLC and like the bike. This is my first e-bike and an expensive purchase at that. Didn't really think about it at the time but when buying a product with newer technology (battery and electric motor) it is critical to buy that product through a manufacturer/US distributor who has good customer service and common replacement parts readily available. When I had questions about battery functionality and availability of warranty replacement of battery still under 2 yr warranty it took 18 days for them to even respond to my emails or phone messages. I moved out of state from where I bought the bike so could not bring it back to the original seller. When contacted that shop and requested a warranty replacement battery they informed me thy did not carry any replacement batteries in stock for Hiabike so the US distributor was the only source. An e-bike is useless when the battery does not work. Living in CHICAGO I have a limited riding season. After waiting a further week between subsequent email exchanges (nobody ever answered the endless hold on the customer service phone number) I was told I could buy a replacement battery for $600.00 plus shipping and handling. They never addressed any warranty claim information. I felt it was important to share feedback about my experience about Haibike for the benefit of those who are evaluating a purchasing decision for an expensive e-bike. There are many choices of brands and models to buy, this is a cool bike but I wish I paid more attention to reviews and feedback about customer service, consumable parts availability and honoring of warranty claims. I am certain I am not the only one who has had issues with the Haibike US distributor!
Jeff, as a Haibike Full FatSix owner, this non-support you speak of bothers me to no end and helps shake my faith in the long term viability of Haibike in the US if they can't be bothered to help their customers when a warranty issue crops up. It was just yesterday I commented on a person's Surface 604 thread, where he was experiencing similar non-running issues. Service after the sale and warranty integrity is going to be a big bug-a-boo for the ebike industry; one they best wake up to soon if they wish to keep growing market share within the US bike industry.
You speak of buying the bike in "SLC". I've no idea what that means. Your issue to me right now appears to be the shop you bought your bike from. I've no experience in warranty repairs nor do I now or ever worked in a bike shop or within the industry. I just like riding my bike!
That shop is the point of contact to the US distributor, not you. Their feet should be held to the fire. It appears they just washed your hands of you and left you to your own devices. And let me say that I cannot imagine any shop giving up a battery such as the Yamaha one, go to a customer without checking the battery, first; for themselves and sending it back for a warranty replacement. From everything I've read and personally experienced with the Yamaha e-drive systems is that they are bullet proof, dead reliable. As a Haibike owner, I wish to stay in your loop about what the final outcome to your situation is going to be; whether people stand up for their product or if they choose to leave you hanging out to dry.
Your Haibike should have come along with a Haibike owners manual and a separate Yamaha ebike drive manual. Do you have them? If not, here is a link to download a very thorough Yamaha service manual for their ebike systems, including a very thorough battery section with checks you can make on your own to determine the status of your battery. This download is much more in depth then what came with my Haibike and what should have accompanied yours. Link:

Did your bike ever function properly in the first place? Did it charge fully on the Yamaha charger? Did you ever drop it? (sorry, have to ask!). Is the speed sensor on the spokes (or is it in the rear brake rotor on your newer Haibike) in place and in line with the sensor? Good battery in the readout display? Wire runs from the display to the controller, down to the motor intact and not cut? How is the charger? Does it light up when you plug into your battery? Is the green light on when connected to the battery?
This summer, I purchased on 2 separate occassions, 2 500wh batteries to supplement my original 400wh battery. Right out of the box, they went on my charger, the charger did it's thing and bit by bit, each red light on the battery came on until she was fully charged and the bms shut the charging down. No problems or issues, 2 different vendors. This edrive system is about the most bulletproof one on the market and your issue seems to be the rare, but unfortunate one to have to go through.
Keep us advised, I want to know how this works out for you. That is a great bike you have there and I have confidence this glitch will get fixed and put in your rear view mirror!
