  • This bike is Tall, big and quick !
Color: Orange 750W (UL Model)
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 on drive unlock 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! ... show more

  • A Lot of Bang for Your Buck
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. ... show more

  • It's Likely Too Big For You
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 footwear and 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!!! ... show more

  • Great value
Color: Orange 750W (UL Model)
You need to try this ebike. I looked at reviews and YouTube videos of all kinds of fat tire cruisers. I decided on ecotric. It is amazing so I bought my son one. Everything about it is nice. Rides great although I’m a big guy 6’ 2” 270 lbs so I bought a different seat. Love the curved handle bars the big tires ride great and the seat even has a shock built in to cushion the bumps. It looks great very impressed. We got a blue one and an orange one. They both stand out. Had to do minor adjustments to brake calipers to keep from squeaking but other than that we love them. I haven’t gone over 6 miles at a time so far but I did 3 six mile trips without charging and it only moved one bar. This is one of the best and fuest purchases I have made. Keep in mind it is very tall bike. I barely fit with seat high enough to make it comfortable to pedal. My son is 5’ 10” and I lowered his seat all the way and he has to tiptoe when he stops ... show more
