    LACROS THUNDER: Long Range Trip

    I biked the entire Greenbrier River Trail in West Virginia on the Lacros Thunder e-bike — an 80-mile adventure from Cass to Caldwell with tent camping, remote river views, spring weather, a trail closure detour, and a whole lot of lessons learned along the way.

  • 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.

Customer photo review of Thunder - Full Suspension Electric Mountain Bike for Sale

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.

Customer photo review of Thunder - Full Suspension Electric Mountain Bike for Sale

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.

Customer photo review of Thunder - Full Suspension Electric Mountain Bike for Sale

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.

Customer photo review of Thunder

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!!!

It is surprised that I got the bike about 3 days earlier than the expected date was.It came nicely packaged, the assembly took about 30 minutes,it was a little messy when we first unpacked it, but we got it done.The seat it comes with, in my opinion, is very comfortable, I am also a bigger person.The headlight is actually really good as well. The bike looks really nice overall, I really like the black. It's a really good bike for the price, and I'm glad I got this one.
