yes

At least it is not a motor or a battery

@mikekazimer: Is there a feature/filter to filter them off the trails? LOL

I hate E-Bikes!

Jarring trails and heavy vibrations can cause severe internal damage to e-bike mountain bike (eMTB) batteries, specifically by cracking or wearing down the internal cell separators. The battery pack is subjected to constant, high-frequency impacts when riding rough terrain, which can lead to cell movement, wear on structural components, and ultimately catastrophic failure if not properly mitigated. The internal separator is a microscopic, porous membrane inside individual lithium-ion cells (and the structural material separating cells within a pack). Its job is to keep the positive (cathode) and negative (anode) electrodes apart while letting ions pass through. Internal Short Circuits: If jarring vibrations crack or wear through this thin layer, the anode and cathode touch directly. Thermal Runaway: A direct short causes a massive, instantaneous rush of current. This generates extreme heat, often leading to a chemical chain reaction, smoke, fire, or explosion. An e-bike lithium-ion battery can catch fire hours or even days after a crash. Why Crashes Cause Delayed Fires Internal Short Circuits: A hard fall, collision, or impact can rupture the internal separator barrier that keeps a lithium-ion battery's positive and negative terminals apart. Thermal Runaway: Once that barrier is damaged, slow internal degradation can cause the battery to rapidly heat up, vent white gas, pop, sputter, and eventually burst into flames—sometimes long after the impact occurred. Deceptive Appearance: A battery can look completely fine on the outside while experiencing catastrophic chemical failure internally.

At 4 A.M., His E-Bike Battery Exploded. Within Minutes the House Went Up in Flames. Rochelle Privratsky awoke first to the sound of the smoke detector screeching downstairs, piercing the stillness of the small hour. She nudged her husband, Matt, who’s a heavier sleeper, then rolled out of bed and navigated to the bedroom door of their home in Saint Paul, Minnesota. When she opened it, smoke billowed in. Before lunging to his feet, Matt looked at his phone. It was exactly 4 a.m. on a September night in 2025. Matt ran outside, herded the dogs into the family’s shed with Rochelle, then made a last trip inside for the car keys, which were only five steps from the back door. By the time the Saint Paul Fire Department arrived minutes later, flames had blown out the dining room window. The fire was completely snuffed by 4:23—exactly 20 minutes after Rochelle’s 911 call—but it had burned with shocking ferocity. The couple’s house was still standing, thanks to its stucco exterior and plaster walls, but everything inside was incinerated or destroyed.

@garybuseysfrontteeth: The Athertons just had their business burn down, seems like a little bit of a "dramatic" event to me.

Got to love these things, nothing like having fire bombs laying around ready to go off LOL The president of the National Bicycle Dealers Association stated that roughly 10% of member bike shops have reported experiencing some form of thermal runaway or battery-related incident in their stores. High-Profile Shop Fires: Major urban incidents have drawn widespread attention—such as a June 2023 fire at an e-bike repair shop (HQ E-bike Repair) in New York City's Chinatown that killed four people when flames spread to the apartments above. Regulatory Enforcement: Local authorities have heavily targeted commercial storefronts; for example, the FDNY conducted nearly 600 shop inspections in a single year, issuing hundreds of summonses for improper battery storage and charging practices.

Getting closer and closer Remove the pretend cranks/pedals add pegs and a throttle and you will be there.

The Honda CRF250R also has a "Motor Gearbox"
