The fork looks great, and fits percectly. I really like the upgrade of the extra support bracing. The only problem is that this fork uses a different derailleur hanger and it was not included with the fork. Looking to get the correct hanger. Thanks, Dan

PU2 and PU3-BB Battery 52V 25Ah Electric Bike Battery

I absolutely love this company! The bike I purchased was a PU1 frame number C6. I have loved this bike from day 1. I find it to be a top quality bike. As a side note I was able to get 1250 miles out of the front inner tube and about 1350 miles from the rear, I stopped by a local bike shop and the owner was amazed, he told me the average he has seen is somewhere between the 600 to 800 mile range. Anyway I ( no fault to Pujh ) was trying to manhandle my bike down some stairs and it got away from me and my digital display on the handle bars was smashed. But no problem, I jumped on their website and ordered me a new one. They shipped the very next morning ( man that’s fast ). I received my new display a day or so later. There are several things I had to program into it for my specific bike that I did not understand I got in touch with support and they walked me through each and every one. So long story short; GREAT QUALITY WITH THIER BIKES, AWESOME PARTS SUPPORT IF YOU NEED REPLACEMENTS, CUSTOMER SERVICE IS SECOND TO NONE! I would 100% recommend them ( and do to anyone who asks about my bike ) to anyone needing a good reliable bike with great customer service to back it up.

PUJH PU3-60V-20ah 26“ Pro Off-road Electric Bicycles

Great customer experience. A few minor issues that were taken care of immediately. Only ridden the bikes a few times, it’s winter and too cold (20 deg. F) for riding. We did put about 4miles on both bikes. Everything worked flawlessly and as described. Would highly recommend and would purchase again. I have not seen customer support like this in 30 plus years.

Great value, beautiful finish, easy to assemble, and very well built.

Very impressive for the price.It has a beautiful finish and frame design.The controls are well placed.This is the second eBike I have put together and it was a dream assembly in comparison to my wife's off brand.I had it together in 30 minutes. Others are complaining about the wobbly handlebars which I also experienced.The front screw is hard to see, but it is in the front, separate from the others and tightens this metal plate that keeps the handlebars in place. It should have some locktight on the screw in the front but I put 20 pounds on it and it stopped moving and hasn't since even after some rough rides. Also, there is another hidden screw in the main fork shaft behind a rubber cap that locks the neck in place.There were only a couple of issues, the back rack needed to be pulled out because the forks did not line up.Took a pipe and slipped it over the forks and bent them out a bit, no problem and nothing to complain about.Battery was fully charged but topped it off anyway. It is quite the power pack and heavy. I road it for about 30 minutes and it did not even drop a bar.I had to unlock the speed governor because no matter what, I could not get it above 28. Youtube vids on that, super easy. I believe the setting is P16. After the computer reset, it still only shows 5 speeds but the fifth will get you to 45.Came with a small air pump, an extra tire tube, a bike lock, a backpack and a little hand held fan with some extra USB cables and that was a nice bonus! Especially the tire and the lock.My Wife's didn't come with anything but busted knuckles, they should have included bandages.That is why I really appreciate how easy it was to put together.30 minutes vs. the cheaper off brand? 9 hours!The power is incredible and yeah it will get you to 45 MPH in a hurry.It is a heavy duty bike. This is not your typical mountain bike that weighs 20 pounds.It is a beast made of thick material and takes a bit of getting used to if you've ridden lightweight bikes all your life as I have.It handles more like a lightweight 2 stroke dirt bike than a mountain bike.However, it has been a long time since I have ridden and can see how I need to build up some skills and muscles.I wish it had more gears which would be my only gripe. The low gear will not be pleasant pedaling up a 6-8% grade if you had no juice in the battery.Highly recommend a brain bucket, riding gloves, knee guards and some goggles or helmet with a visor.Bug in the face at 45 stings, 45 to 0 downright hurts.Overall, Hats off to PUJH, pujhebike . comGreat job!

A VERY NICE BIKE, READ MY REVIEW!

THIS BIKE APPEARS TO BE VERY WELL MADE. IT WILL TAKE SOME TIME TO SEE IF IT WILL TAKE THE TEST OF TIME FOR LONGEVITY .THE BIKE WAS PACKAGED VERY WELL AND WAS VERY EASY TO ASSEMBLE, ALL PARTS WERE INCLUDED AND THE ASSEMBLY DIRECTIONS WERE VERY EASY TO UNDERSTAND. THE ONLY PROBLEM I HAVE FOUND SO FAR IS THE HANDLE BARS WILL NOT STAY TIGHTENED TO THE HANDLE BAR STEM, I TIGHTEN THE BOLT AND IT COMES LOOSE VERY SOON AFTER. THE BIKE IS A BEAST AND RIDES VERY WELL! IT HAS LOTS OF POWER AND SPEED! THE BATTERY IS LONG LASTING IF YOU DO NOT HAVE THE THROTLE IN HIGH SPEED ALL THE TIME. THE SUSPENSION GIVES YOU A COMFORTABLE RIDE! AFTER SOME TIME I WILL RETURN TO THE REVIEW AND MAKE COMMENTS HOW THE BIKE IS DOING OVER TIME.

I absolutely love this bike from the time I ordered this bike till the present. I was delivered to my door with in a couple of days. The way they packaged it was awesome nothing was damaged, everything was intact. It took a couple of hours to put it together (took my time) I did need help with the front wheel ( nothing major) got it together and away I went. All my friends took turns riding it,they were so impressed that one guys is going to purchase one with his tax return. I haven't taken it on any trails yet,but I will soon. I've been on the streets with it and dose really well handled well on bumpy streets brakes are great it's a head turner for from young to old. Very happy with the whole package!!!! Thank you PUJH

My extra battery is just the same as the original, but without the stickers. Almost doubles my range, except all the extra weight of the battery. It also cost a little more than a third of the total bike cost. Crazy that they can build a bike this affordably.

I love this bike. Easily one of the best purchases I have ever made.

Really nice bike. If you’re looking for a good bike w good performance for a good price, stop looking. This is my third ebike and it’s a good value for good quality. I hit 43mph the other day on my ten mile commute to my shop. My experience is they get faster as you use them. Front hub so powerful it spins on dry road if I juice it too much. I like it!!

For the money you can't beat it, very nice soft full suspension, I compared this bike to the Tuttio Adria 26 5k watts as well, which had very stiff suspension no movement really and the motor was on a delay which is not good when climbing really steep hills, The PU3 gives all that power almost instantly in comparison to the tuttio.
