If your e-bike has a hub motor, you’ve probably felt resistance when you pedal without power—that drag is the motor turning into a generator. A clutch solves that. In an e-bike, a clutch (usually a one‑way bearing) disconnects the motor from the drivetrain when you stop pedaling or when your cadence exceeds the motor’s RPM,…
The e-bike speed controller regulates power from the battery to the motor using a handful of critical components: MOSFETs, a microcontroller, capacitors, and a voltage regulator. Knowing what each part does helps you diagnose a dead controller, choose a reliable replacement, and avoid buying a part that won’t fit your motor or riding style. This…
Giant e-bike batteries are covered by a limited warranty that typically lasts 2 years from the original purchase date for model-year 2023 and newer bikes. The warranty protects against manufacturing defects such as cell failure, internal charging faults, or swelling from defective cells—but it does not cover damage from misuse, normal wear, improper charging, physical…
Torque is the rotational force that determines how well an e-bike climbs hills and accelerates from a stop, measured in newton-meters (Nm). It matters more than peak wattage for real-world climbing ability: a 500W mid-drive with 100 Nm will outperform a 750W hub motor with 40 Nm on a steep grade, even though the hub…
Trek e-bikes use four motor partners—Bosch, Shimano, Fazua, and TQ—not a single in-house unit. The motor you get depends on the model and riding style. Bosch powers Trek’s heavy-duty electric mountain bikes and commuters; Shimano appears on mid-range and urban bikes; Fazua and TQ drive the lightest, most natural-feeling e-bikes in the lineup. If you…
The right controller size for your e-bike means matching voltage exactly, staying within the motor’s current limits, and picking features that match your riding goals. A mismatch can cause sluggish acceleration, overheating, or permanent motor damage. Here’s how to pick the safe, effective size for your setup. Voltage Compatibility Is Non-Negotiable Your controller’s voltage rating…
Torque is the twisting force that turns your e-bike’s rear wheel. For Bosch e-bikes, torque directly determines how hard the motor pulls when you pedal—especially from a standstill, up a hill, or when carrying cargo. Higher torque means stronger acceleration and better climbing ability without having to crank as hard yourself. Bosch offers several drive…
If you own an e-bike you no longer ride, the platform you choose to sell it on directly determines how much cash you walk away with, how much work you do, and how fast the transaction happens. There is no single best option—only a best option for your specific situation. Do you want cash today,…
The Class 2 sticker on a California e‑bike is most often located on the frame near the bottom bracket, on the downtube, or on the seat tube. California law (AB 1096) requires this sticker to be permanently affixed and clearly visible. If you are searching for yours, start with those three spots, then check the…
