How fast would a 72V 4000W ebike go?
So, how fast is a 4000w ebike? On private property or closed circuits, a properly tuned 4000w electric bike kit with battery can reach speeds of: 80–90 km/h (50–55 mph) depending on load and terrain. With pedal assist, even higher short-term bursts are possible. A 72v 5000w motor can typically reach 40-45 mph (64-72 km/h) under standard conditions. Optimized setups and favorable terrain can allow speeds up to 50-60 mph (80-96 km/h), with peak cases approaching 80 mph (129 km/h), making it ideal for high-performance e-bikes and street-legal electric motorcycles.
What is the lifespan of an ebike?
If you’re considering an electric bike, one of the most important questions to ask is: How long does an e-bike last? While the lifespan of an e-bike varies, a good-quality, well-maintained ebike can typically last 5 to 10 years, sometimes even longer. Replacing an e-bike battery typically battery cost is between $400 and $900, depending on factors such as the type of battery, its capacity, brand, and place of purchase.Average lifespan: A high-quality e-bike battery should last 3–5 years, or roughly 800–1,000 charge cycles before capacity drops below 70%.Most e-bike batteries fall somewhere between $300 and $800, depending on the type and brand. Some high-performance models can climb well past $1,000, but that’s not always necessary.The short answer: no. The ideal state of charge of an e-bike battery is not at 100%. This is because a complete charge puts the electrodes under very heavy stress.
What are the disadvantages of an electric bike?
Electric bicycles require regular maintenance to ensure they work properly. Electronic components and batteries can be expensive to maintain and repair. Battery failures, motor problems and repairs to electronic control systems can represent significant additional expenses. Bicycle theft is a severe problem in the US, and electric bikes are among the bike models that are the most likely to get stolen. The exact number of stolen e-bikes is hard to get by. According to the study done by Project 529, about 80% of bike theft victims didn’t report their crime to the police.E-bike riders may often be older and inexperienced cyclists. This combination of speed and potential physical limitations, along with the heavier weight of e-bikes, increases crash and injury risk.
