Lacros Thunder Review: Big Battery, Big Brakes, Big Value
The Lacros Thunder is a lot of ebike for the money. It packs a big 960Wh battery, a strong motor, full suspension, and reliable hydraulic brakes. It climbs steep hills with ease, and the cadence sensor is tuned really well. It's (obviously) heavy at 83 lbs, and the rear shock has no adjustment, but I struggled to find much else to complain about.
In this video, we dive deep into the Lacros Thunder, a powerful and stylish electric bike built for performance, safety, and everyday commuting. From the full unboxing and setup to a detailed look at its components, design, and real-world riding test, we cover everything you need to know about this e-bike.

I am overwhelmed with quality and performance of this ebike. It was very easy to assemble. I am also impressed with the comfortable ride. This is my new best friend. Thank you Lacros for the care and expertise you put into this ebike. It's Awesome!
Absolutely Blown Away by the Thunder!
From the moment I unboxed the Lacros Thunder, I knew this bike was something special. The build quality is top-tier — rugged, sleek, and clearly made for adventure. The full suspension system makes off-road riding incredibly smooth, even over rough trails and steep climbs.
The motor packs serious power, giving me the confidence to take on hills and long distances without breaking a sweat. I was impressed by the torque and how responsive the pedal assist is. The fat tires offer amazing grip and stability, whether I’m riding on gravel, dirt, or sand.
Battery life? Outstanding. I went on a long day trip and still had plenty of juice left. And the design — it turns heads. You get the best of performance and looks in one beast of a bike.
Whether you're hitting the trails or cruising through the city, the Thunder delivers. Highly recommend to any serious rider looking to elevate their game.
This bike is awesome! I am using it to travel in a downtown area where I live. I’ll still try to get my 5 miles of steps a day, and for extended distances hop onto this e-bike for timeliness and punctuality, to meet my commitments a walk might not. In addition, it’s beautiful. The tires are Fat/Thick providing confidence in the ride. The shock absorber lessens the impact of a bumpy ride, feeling smooth and carefree. To be honest, I don’t even pedal! I ride it like I would any vehicle.
With this vehicle pivot to an e-bike, I sold my car. No more gasoline expense, car/finance payment, insurance, maintenance, DMV registration fees, I venture to say I save myself $10k per year. Be a prudent driver, because this e-bike is fast as bikes go.

Sorry Valerie, actually every bike is tested before being packed and then the test marks were removed, this one may not have been removed accidentally. We can guarantee that all ebikes we send are brand new !
The box was well protected and bike was well wrapped.
Just put the bike together and charging the battery now. First thing i noticed when i opened the box is the back rack was scratched and scuffed other than that it arrived in good condition. Assembly was pretty easy.I had to completely turn the post around because the handle bar assembly was in the wrong position. There were no instructions for the front fender and one of the screw holes was stripped. Hopefully it won’t rattle and I can fix that.

Got my E bike.Charged the battery went out for a little ride on the Pinellas Trail here in Florida. It was pretty easy to ride then I took it up one weekend to a property up at a hunting area with a lot of sugar sand, and it was a little hilly, but this thing went right through all of it. I was pretty impressed. Went out to check cameras in the woods and it took 25 minutes! Walking takes 1 1/2 hours. This is a game changer for hunting!!!
