Do not order from this company. I fell for it on the last deal and it has been an absolute nightmare.

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…

Stay as far away from Mendham Bikes as you can. HORRIBLE company. I trust SD's and have never been burned....until the last Mendham deal. It's been a horrendous and miserable experience that has cost a dozen or so hours thus far.

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.

It's mid-drive. They require substantially less power than hub drives. They also tend to be more expensive than hub drives.

Quote from townes75 :
I took mine to my local bike shop on Friday and they just pulled it out of the box and found that the fork was damaged. They recommended that I contact the seller and have them send me a new fork. I spoke to customer service, and he asked me to send him photos of the damage, and then he said he will check with the warehouse "down south" to see if they have a fork for this particular bike and that he will get back to me in 1-2 business days. I expressed concern about the 10 day return window and he said since I talked to him "it's good" and that I "don't need to worry about it".. I guess I'll give him the 2 days and if he doesn't get back to me I'll have to send it back. Below are the pictures the shop sent me..Does anyone know if the return shipping is free?Thanks!
So did you hear anything back from them? Also which customer support number did you use?

So, I dialed the Kent number (1-800-451-5368) and they could not find an extra fork to ship to me. They did offer me a $100 credit to "source" a fork through my local bike shop but they had none and could not source one that fit this particular bike. My local bike shop is also charging me $70 for labor since they got half way through before noticing the damaged fork, and then had to disassemble it to put it back into a box (not the original box because it was so damaged that they threw it away). I have now filled out the form for a refund but also asked (through email support) if they will cover the $70 in labor. What a hassle..

Apologies if this is a newbie question. But how do i shift down gears on this. When I click, I was able to move up the gear, but not aware of how to do it reverse? Thank you in advance

Well I've spent a little time with this bike and here's some thoughts:

1. This is a "project bike" (at least mine is). It's going to require some bike wrenching abilities plus knowledge/experience or the willingness to learn. Mine's definitely not a turnkey, ready-to-ride after assembly type of bike. It'll take some time and effort (and new parts) to get it dialed in.

2. The brakes are absolutely crap. Mine was shipped with Radius brand hydro brakes that were non-operational and unsafe as delivered. They cannot be easily bled (no bleeder valve) and my front brake is leaking oil. We can't really test drive the bike at speed as the lack of front brake makes it too dicey.

3. And while I thought my bike arrived relatively unscathed (aside from broken reflector and minor scratches) the front rotor is bent up pretty bad and probably not salvageable.

I'll be contacting Mendham to figure out a resolution to the rotor and bad brakes issue.

4. The good news is that it looks like these bikes already come with the ability to adjust speed limit (not tested as yet) and wheel size through the display.

5. The bikes also come programmed with both an Eco and Sport modes, each of which has its own 5 levels of PAS. You can set your default mode through the display or switch modes by holding down the + button on the remote. Pretty cool.

So at $450, I think these were a decent deal on a project e-bike. Certainly not worth anything more than that - especially with the condition and issues we've all been experiencing.

I'll update this thread as I learn more and seek some help from Mendham. But I don't think we'll be selling my wife's Yamaha CrossCore for awhile after all…

if you mean petal assist, just press the +/- buttons to increase and decrease PAS respectively. If you mean rear derailleur, the shift on your right has two buttons, one for the thumb and a second lever behind it for changing gears.

More thoughts / notes

The charger is about the crappiest little thing they could build that still outputs power. It inspires zero confidence in the build quality so I'll be charging this battery outdoors for a while. My electric skateboards have much beefier chargers for much smaller batteries.

The battery is easily removed and can be charged off the bike as it has a charge port in one end. The large terminals on the battery base are two positives and two negatives. I'm not sure of the function of the brass pins at the base of the battery. They mate with corresponding pins on the bike. They may be pins for a battery temp sensor as they did not have voltage across them like the others. Based upon my initial observation, I think it will be pretty straightforward to wire in an auxiliary 36v battery should the need arise. Seeing as this will be my wife's bike, that is doubtful.

The controller should have sockets for wiring in lights that can be controlled from the remote, but in reading, these look to be 6v 500mA - so not a lot to work with. Probably better to use those to trigger a relay to more powerful lights powered off the battery.

That's all for now.

Thank you. My question was specifically related to rear derailer. When i clicked the one for thumb, I see the numbers incremented to 1 to 8. How do i get it back to 1? The rear lever doesn't seem to do anything when i press it or does it only downshift while riding and not at stand still?

Pressing the thumb button should get you back to lower gear(1, larger sprocket). The back lever shifts you to higher gear(8, smaller sprocket). If pressing the thumb doesn't do anything, it could mean your rear derailleur needs adjusting. This video is useful https://www.youtube.com/watch?v=UkZxPIZ1ngY

I have another question. I do understand that the website mentioned that the bike has hydraulic brakes but I feel it does have just regular mechanical brakes instead of hydraulic brakes. How do i confirm its hydraulic brakes?

If it's mechanical brakes you'll see a twisted metal wire running to the brake calipers and it'll be terminated with a small numb sticking out. Also if you've ever pulled on a mechanical brake vs hydraulic you can also feel the difference. hydraulic feels slightly more 'mushy'.

Our community has rated this post as helpful. If you agree, why not thank snowranger69

I received mine today and just assembled it. It took me about 1 hour to do. The only damage was the cracked rear reflector and some paint scuffs on the fork. The brakes are radius brand hydraulic brakes that take standard Shimano style brake pads. There is a bleed valve on them.

Very easy assembly. Mount front wheel with supplied skewer. Engage kickstand to make work easier with a standing bike. Pump up tires, mount front disc brake. Pay attention to the order of spacers. Partially tighten mounting bolts, press brake lever to seat pads, and further tighten bolts. Mount handlebars with 4 Allen bolts. Screw on pedals, adjust seat. It appears that derailleurs were already adjusted okay

Also you need to push the battery button switch to on before you can power up the controller. I guess I lucked out. This is an incredible deal

I just unboxed mine and the fork is misaligned so that the front wheel touches the edge of the fork on one side. Ugh. Can a bike shop fix the fork? The bike seems pretty nice in general but the packing was definitely insufficient
