    5.0 out of 5 stars Impressive Performance and Value – Exceeded Expectations!

    T. · June 9, 2025

    The media could not be loaded. Impressive Performance and Value – Exceeded Expectations!I’ve put over 200 miles on this bike across a variety of terrains, from mountain trails to soft sand and it continues to exceed my expectations, especially for the price.Pros:• The 26” x 4” fat tires make riding over obstacles effortless. Whether it’s sand, gravel, or rough trails, this bike handles it all with ease.• It’s a tall bike, which makes it an excellent fit for riders over 6 feet tall.• The battery life is impressive. I regularly ride 30 miles on assist level 5 and still return with two bars of power left.• The seat has a beach cruiser design with built-in springs, making long rides very comfortable.• The ergonomic grips include palm rests, which make throttle control more comfortable and natural.Cons:• The handlebars can slip if too much downward pressure is applied.• I had to adjust the front brake to prevent it from rubbing.• The seat arrived with a tear, but customer service handled the issue quickly and professionally.• At around 200 miles, I noticed the rear axle nut had loosened significantly, something to watch out for and regularly check.• The brake lever retention screw tends to back out, requiring occasional tightening and adjustment.Overall:I’m really happy with this bike. It rides well, feels solid, and turns heads everywhere I go. I’ve gotten a lot of compliments, and with a few minor adjustments, it’s been a great investment.

    5.0 out of 5 stars Easy to put together very nice bike!

    The bike came 85% done and was easy to finish putting together. The instruction book was easy to follow and made things clear. Nice bike!

    5.0 out of 5 stars A Lot of Bang for Your Buck

    S. · March 8, 2023

    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.

    4.0 out of 5 stars It's Likely Too Big For You

    T.T. · October 20, 2021

    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 Bolo. 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!!!

    I considered purchasing a kit to conform my mountain bike into an electric bike. After researching many options, I realized the cost was comparable to the purchase price of a brand new e-bike. I am over six feet tall and weigh about 280 pounds. This bike has performed great! Very comfortable on rough terrain. I modified the bike with new straight handle bars and a taller neck. I mostly ride it on paved roads and mild bike paths. Very satisfied with the performance compared to the price. Most e-bikes only go about 20 MPH. If you are interested in making additional modifications, online videos can show you how to adjust the settings to allow you to increase top speed. Even with my weight at 280 lbs. my top speed with throttle only reaches 28 MPH. Hope this helps and highly recommend this brand and model.
