ECOTRIC Coolboy Electric Bike 26" Fat Tire 750W Electric Mountain Bike 48V 12.5AH Removable Large Battery Adult Electric Bicycles Beach Snow Mountain Bike Dual Shock Absorber & Shimano 7-Speed

Alright, gather 'round folks, let me tell you about my ECOTRIC Coolboy Electric Bike with its 26" Fat Tires – this thing is the Chuck Norris of e-bikes! I've had it for about half a year, and it's more reliable than a squirrel gathering nuts for winter.First off, hitting the local trails on this bike is like strapping a rocket to your back, but with way better handling. Mud, rocks, small bushes – I'm pretty sure it would ride over a sleeping bear if I asked it to. The fat tires? They grip the ground like they've got personal beef with gravity.But wait, the plot thickens – one of the batteries went kaput. I was like, "Oh no, my electric steed has a flat tire!" But here's where ECOTRIC becomes the hero of our story. I contacted their customer service, half-expecting the usual runaround. Instead, what I got was service so fast and friendly, it's like they were my neighbors, just waiting to lend a cup of sugar. Or, you know, a bike battery.In a nutshell, if you're looking for an e-bike that'll turn your trail rides into epic quests and back you up with customer service straight out of a feel-good movie, the ECOTRIC Coolboy is your ticket. It's not just an e-bike; it's a faithful trail-tackling companion with a support team that's got your back. So, grab your helmet and embrace your inner trail warrior – with the ECOTRIC Coolboy, the adventure is just beginning!

The bike arrived boxed with plenty of foam internal. Assembly was easy if you know how to put bikes together with hand tools.Many of the secure points are allen type bolts (BE VERY CAREFUL WHEN TIGHTENING AS NOT TO STRIP THE ALLEN BOLT HEADS) they are easy and soft to strip. The written instructions are easy to follow. The battery assembly has a handle and easy to place but its a tight fit. Following instructions on LCD display connect and turn on battery and plug in the unit cord to the display and set your PAS power to 5 for fastest speed or 1 slowest.Yes u must have battery key in always to :turn ondriveunlock to remove battery. Key must stay in on drive mode to operate...i zip tied the key with a quick release to prevent key loss and easy lock and removal of key battery. (2) key only i re-keyed for 2 more as backup.THIS BIKE IS NOT FOR SHORT PEOPLE. I'M 6'1 260lb AND ITS A TALL BEEFY PROFILE.if you get the free fenders do not install them they dont fit to spec, buy the fender and rack combo offered for this 26 inch bike through Amazon.Finally.... its fast, the throttle is quick and holds speed at first start.This is a beautiful beast, strong frame but recommend a rubber gasket for the yoke spanner for the handlebar to prevent loose handle bar and make it tighter.This beast is a keeper!

This model should be named The Beast, although The Hammer is pretty intimidating, as is the bike itself. These bikes need to come in a 24" wheel option, they are too tall with 26" wheels for anyone less than 6' something, unless they are used to riding motorX motorcycles and tippy-toeing. I'm 5'11" and had to replace the suspension seat post to get the seat low enough to mount the ride on tippy-toes (added expense #1 of several).The Hammer is not a ride to be considered usable without the epower, it's beyond "sturdy". With the battery on the bike, it is too heavy to lift out of the box safely. TAKE THE BATTERY OFF WHILE IT IS STILL IN THE BOX, or rip off the side of the box. You might as well get the charger out and start charging the battery straight away.The assembly is uncomplicated enough to be done on a 6 pack after me and Tom did the NFL and PGA on a Sunday afternoon. Though check your work in the morning, after you are fully lucid and the battery has charged overnight. When you slide the charged battery onto its rail in the morning, you must make sure the rail is properly adjusted so that THE BATTERY SEATS FULLY FLAT ON THE CONTROLLER WITH THE PRONGS FULLY INSERTED. This is critical since the rail may not come adjusted in the box and may lead to trying something silly like opening the control box looking for loose wires.THE HANDLE-BARS ARE A PROBLEM! Either the headset can't be tightened to keep from moving or the handlebars themselves slip in the bracket. I was able to tighten the handle-bars enough (it takes nearly snapping the hex wrench), although I ended up using epoxy to secure the headset angle. This is not right and the manufacturers need to correct the issue.Riding the Hammer is a blast, it goes off-road with ease, though the chain rattles too much for rock hopping. There is a learning curve to get the riding technique right. It's too heavy to safely, in traffic, go from a full stop without using the throttle by only gearing down. The ride is closer to riding a moped than riding a bicycle and it is easy to get into trouble by thinking you are riding a bicycle. 20 mph sounds slow, yet for someone without motorcycle experience, it's fast for a bicycle. For those with motorcycle experience, you will want more speed after your first ride and be looking for how you can remove the 20mph speed restrictor. I'm looking at adding a powered fat tire front wheel as well, though I should likely just ride the 250 thumper if getting there fast is an issue. Excercise wise-fagitaboutit making a difference on your iWatch. You will burn more calories than you do on the couch, but you'd burn more by cooking and serving dinner for four, or walking your dog down the street and back. Word up.The Hammer is a fun, fun, fun machine, other ebikes are better suited to commuting and shopping. They won't inspire the tendencies of adventurous individuals to see how far it will go. I can't imagine what my husband would do to my new Hammer.By all means, when it comes to getting the brakes and derailleur set up perfectly, take it to your local bike shop to professionally get 'er done right. Or order the expert assembly. Getting the brakes to not rub is critical, although the 7 gears are really not that important. The bike is not ridable for long on human power alone. Maybe at 70, I have a different perspective than you will about that.First and foremost, buy a helmet and protective gear, never ride the Hammer without proper footwearand clothing. Think of it as a motorcycle, 20 mph road rash is serious, your head will split if it hits the pavement or a boulder at 20mph. You will need fenders, I was covered in sand after a beach ride (super fun), if it were mud it would not have been so fun. I ordered after-market fat tire mountain bike fenders, they look like motorX fenders. You will likely want a rack on the back, and most definitely something louder than the insulting little bell included. No real woman or man would ever attach that insipid bell to any bike-unless it's used to goose pretty girls and boys on the beach. I bought a horn from Amazon. You will want a lock that is up to protecting your substantial investment-nothing stops an angle grinder though, so you should be aware that your Hammer will be lusted after, and take appropriate cautionary measures. You might be lusted after as well-or more lusted after, as in my case- as you ride your beast. THIS IS A SERIOUSLY COOL MACHINE, I can't wait to get rid of the goofy race decals and paint it camo to match my boat AND ditch the speed restrictor. I might even get Tom off his Harley if it will go faster.In conclusion, The Hammer was a 70th birthday present from my husband. It is not a "plug and play" machine, ladies-you might need your man, I did not. I am a big girl and my sweety pie can't turn a wrench without skinning up his knuckles and cant play golf. You should expect to spend up to $500 after you put it together. YET, IT IS WELL MADE AND WELL DESIGNED! It should last for many years as a beefy adventure bike and an eye-catcher. JUST LIKE YOU!!!

This is my second Ecotric, one stays at my Florida home and this new one stays at my Richmond, VA home. In Richmond I needed the 48 volt version to tame the hills. In Florida, the 36 volt version works fine on the flat streets. As others have said, this is a heavy bike that requires legs with an in seam of approximately 30 inches to allow the "giblets" to clear the bar when you are stopped. The power and ride quality of this bike is incredible. The OEM seat is my first that didn't need changing out. It is very comfortable. The components are well made and heavy duty. The only fly in the ointment is the handle bars. No matter what you do they will not tighten up securely at the center spindle. This allows them to shift up and down at important times when you need rigidity. After looking online, I decided to drill and tap a 1/4" hex head screw down through the handlebar. This fixed the issue completely. There are other online ways to fix the problem, so don't let this change your decision to purchase the bike.
