The first bike arrived damaged and unusable. They refused to honor their return policy, insisting that I either repair it myself (they sent me a link to a YouTube video wtf) or bring it to a mechanic at my own risk. Suffice to say, I opened a credit card dispute and am still fighting to retain my credit.
The second bike hadn't been shipped when the issues with the first began, so I requested a cancellation, which they confirmed. Then they shipped it anyway. I refused the delivery. It arrived at their facility 2 weeks ago and I still haven't received a refund. Another dispute was opened and I'm having to deal with that now.
Edit: just checked and the first dispute was finally resolved in my favor just this morning. Now on to the second dispute…
I ordered one of the Able bikes in the last deal. About three weeks went by between the time of the order and when I realized I hadn't received the bike. Meanwhile, they spammed the heck out of my email account with other "promotions". I emailed the general customer service email address demanding they provide me an update. No response. About another week goes by and I get a "your order shipped" email notification. Great! Fantastic! Except that a few hours after receiving that email, I got a retraction saying they had made a mistake and my order hadn't shipped.
I emailed them to demand cancellation of the order based on the long wait and my spidey senses telling me something was off. I actually got a response within a few hours that acknowledged my request and told me the order would be cancelled. Guess what? The next day, Mendham shipped the bike. Geez. When I got the shipment notification, I started checking the tracking and noticed it took them more than a day to actually ship the bike (they just issued tracking by creating a shipping label). In the interim, I again emailed them about cancellation and warned them not to ship. No response. The bike arrived and box and interior parts were beat to hell. I put in a dispute with my credit card company, who immediately issued a confirmation of successful dispute, a sign they know what Mendham is up to. I tried several more times to demand they take the bike back. They finally responded on the third email and asked for a huge list of items. I took the bike to a charity that fixes up bikes and gives to kids in need. I'll just rely on my CC underwriter.
Please save yourself from the same headaches and from having to write an equally painful testimonial on SD by just skipping this "deal". It's not a deal and if you research online, you find the bikes are junk anyways.

I just completed a capacity test to the battery's low voltage cutoff point. From full to LVC was 10.93Ah capacity out of a claimed 11.6Ah. So the initial test shows this battery has degraded ~5.8% from calendar aging.
That's not great, but not as bad as I feared since my battery showed up fully discharged. There's a chance it may improve a bit through the first few cycles but I have my doubts.
I may cycle it a few times while I wait for a resolution on my brakes and shipping damage issues. I'll report back if anything changes.

That's good news!
Did they offer to pay for shop labor to do the swap or are they expecting you to do the work yourself?
I'm sure some folks will have the ability to do it themselves but maybe not everyone.

I wouldn't get too caught up in motor wattage specs. It is mostly whatever the manufacturer wants to claim it is and programs the controller accordingly - and these are all nominal ratings. Actual measured ratings will vary greatly.
So at 36V and 250W the controller should be programmed (or using the appropriate shunt) to provide just under 7A of power. At 350W it would be 9.7A. Same hardware different programming.
But wait, there's more…. The stated watts is really more about what the motor manufacturer says the motor is safe to run at for an extended period of time. You can push 2000W through a 250W motor - just not for long. Every e-bike motor will surge above its rated/programmed capacity for a short period of time until the controller gets warm or ramps down the power. You may get 500W at the start of a hill on a 250W bike for a short while. But once on the flats the bike will settle into a lower wattage consumption per its programming.
Keep in mind that EU specs require a PAS bike to be limited to 250w nominal so that is probably why these were re-rated to 250W. It's all a bit of a smokescreen in reality. I doubt they actually made any changes whatsoever.

So, when the new fork comes (fingers crossed), I will take it to the bicycle shop, and they will reassemble the bike and calibrate it, etc., for the $90-$100 they originally quoted me at.
I'm guessing you removed the rear caliper when bleeding? Otherwise it's probably hard to do if the port happens to be on the side.

They are sending you a replacement fork? I wasnt offered that option on our 4 bikes that all came with bent forks.
I just called Kent's support number regarding my misaligned fork. They also informed me they have replacement fork available. I emailed them couple of photos showing the fork problem. My claim is processing now and the rep said it should take a day or two. I'll report back how it goes.
It stinks that a bunch of us are having to deal with issues, but at least in my case, Kent is stepping up to create a fair outcome.
