E-bike tools & calculators

Five free tools that answer the questions people actually ask before buying an e-bike: where you can legally ride it, how far it will really go, and whether it beats the car. No signup, no black box, every number sourced.

Questions people ask

Which tool do I need?

Which tool tells me where I can ride my e-bike?
Ride Check. Pick a bike we have reviewed and your state, and it answers for five surfaces: road, bike lane, shared-use path, sidewalk and natural-surface trail. Road, lane and path come from state statute. Sidewalks are set by your city and trails by the land manager, so those two name the authority instead of guessing. Open Ride Check
How accurate is an e-bike range calculator?
Ours returns a band rather than a single number, because real range swings with rider weight, terrain, assist level, tyre pressure and temperature. It models from battery watt-hours and measured consumption tables instead of repeating the manufacturer's claim, which is almost always a best-case figure. Open Range Calculator
Is an e-bike actually cheaper than driving?
For most commutes under 10 miles, yes, and the calculator shows the payback month rather than an annual total. It uses EPA fuel-economy averages, current fuel and electricity prices, and your own commute distance, then reports 5-year and 10-year net. Open Savings Calculator
How do I check if my e-bike is street legal?
Enter the rated motor wattage, the top assisted speed and whether it has a throttle. Those three specs decide the class, and the class plus your state decides legality. Use this one for a bike you already own; use Ride Check for a bike you are considering buying. Open Legality Checker
Can I put e-bike law information on my own site?
Yes, free. The embed tool generates a copy-paste HTML badge that links your readers to current, statute-cited e-bike law for all 50 states. It is plain HTML with no script, so it will not slow your page down or track your visitors. Open Embed a Law Badge

The method

How we build these tools

A calculator is only worth what its inputs are worth, so all four of these are things you can check rather than things you have to take on trust.

  • Sourced, never invented

    Every constant comes from a named public dataset: EPA fuel-economy averages, EIA and Ofgem energy prices, Bosch e-MTB consumption tables, and the PeopleForBikes state-law tracker.

  • No black box

    The formula is printed on the tool itself. Open the "How it works" panel on any calculator and you see the exact constants and ratios that produced your number.

  • Dated, so you can check it

    Each tool shows when its data was last reviewed, so you can verify it against current law, fuel prices or grid intensity rather than trusting a figure with no age on it.

  • Reproducible by URL

    Enter your numbers and copy the address bar. The query parameters are documented on every tool, so a result you share is the same result the other person sees.

Looking for the bikes?

Every tool here deep-links into the same reviewed catalogue, so a result always ends on a real bike with a live US price rather than a shrug.
