It's summer now and it's hot. The way to my office is up-hill (half of the way is off-road). With my health it's not a good idea to work hard physically in such whether. And there is no shower in office. So could you please describe main criteria of choosing a bicycle that allows getting up-hill with less effort? I mean the tradeoff between speed and force - I want to reduce force. I would appreciate two options (without engine): less and more expensive.

  • By "engine" are you also excluding electric motor assist?

  • Note that, after eliminating wind resistance, etc, you do the same amount of "work" (from a physics standpoint) going up a hill, no matter how fast you do it. If you climb the hill more slowly (due to "easier" gearing) you (to a crude approximation) expend the same total amount of energy as doing it quickly, but the "level of effort" is lower (and of course it takes longer). However, there is a minimum practical speed for a 2-wheel bike which is about 4mph, so you must go at least that fast. Jul 5 '15 at 1:42
  • Welcome to Bicycles @Parfen. I have edited your question to try to make it clearer. If I have changed your intended question, please revert my edit. The only way of climbing a hill with less pedal force is to climb more slowly. Either use lower gears (big on the back, small on the front), or find a path that rises more gently.

Uphill - gears and weight. Extending the lowest gear range till its faster and easier to walk and push the bike is cheap and easy and would be the first thing on my list to do.

Cutting down weight (of the bike) is an has an exponential cost/gram relationship - you quickly get from $1/gram to $100/gram. Cutting your weight does not require the cash, and in most people cases a very effective way to gain speed uphill. (Shaving 5kg off a bike will cost $1000's, even if possible, many people can afford to loose twice that).

Although you said no engine, in your situation (hot, uphill, no shower at end, health concerns) a pedal assist electric bike would be a very effective way to achieve your apparent aim. Would you be prepared to rethink that position and consider an eBike?

  • To add to that: A proper, efficient seating position and a bicycle with little losses (properly oiled chain, tires with low rolling resistance, locked or no suspension) are also important.

  • Thank you. bicycle with electric engine is very interesting - but I see there is a fashion and that this branch is emerging. So, I'm waiting until prices stabilize. Or you think that this product is matured already and prices will not decrease in next years?

    That is worthy of its own question. The technology is actually quite well established. (electric bikes are not new). Battery tech from auto industry has made them affordable and practical (size and weight). Price will come down a little, but unlike most cycling advances, this market is being driven from the bottom up, where price matters. At the better quality end there is still enough competition to keep the supply chain honest.

  • Also consider cool, comfortable clothing that wicks away sweat – it is not the same as lowering the power requirements for climbing the hill (which is what I think you're asking about), but it can really help with the perceived effort. Also as @mattnz pointed out, you'll quite likely to find that you're getting into better shape and the hills will magically become easier :-)

  • I think this is a good answer. The right bike makes a difference, no argument, but going uphill requires effort, sometimes a lot, and no bike can avoid that.

As a practical matter you really have only two options:

  1. A lower gearing range. This means a smaller chainring in front and bigger cogs on the rear wheel. Batman nicely outlines this in his post.
  2. An external power source such as an electric motor.

A lighter bike will NOT make a big difference. If anyone cares to argue this consider the following: The average bike at the 1982 Tour de France weighed ~21 pounds. The average bike at the 2012 Tour de France weighed just over 15 pounds. That's a more than 25% reduction in weight. Despite this drop in weight (and MANY other technical improvements to the bike) the average speed of the 2012 Tour was only 4% faster (and the Tour was shorter in 2012). Keep in mind this is with the fittest riders on the planet. You can cut the weight of your bike in half but you'll only net a performance increase in the single digits.

Dropping the range of your gears is a relatively inexpensive approach. Even if you purchased new derailleurs, chainrings and gears you'll still spend less than what it would take to buy a new bike. The downside? Well you still have to pedal. You'll be expending less effort which helps you from arriving at the office a sweaty mess but you'll also be taking even longer to get there.

E-bikes are great. You can ride up all but the steepest of hills with very little effort. Riding to work without breaking a sweat is definitely a reality. I'll admit that as a road rider of 35+ years I cringed when I first saw e-bikes but then I got to borrow one for a couple of weeks. It's a game changer, pure and simple. My commute home involves a gradual, mile long climb. Most days I get home I'm pretty sweaty and tired when I get home. On the e-bike I completed the same ride in less time and never broke a sweat. I've also seen moms pedaling uphill on cargo bikes carrying two children without breaking a sweat AND they're keeping up with solo riders on conventional bikes! The other area where e-bikes are pretty awesome is stop and go traffic. Getting back up to cruising speed with a push from the motor is less taxing than relying on pedal power alone. On downhills and flats the e-bike makes little difference as the motors essentially top out at 20mph. The motors on e-bikes are really intended more as a supplement to pedal power, not a replacement. They're not electric scooters as some people seem to think (some designs won't even work unless you're pedaling).

Downsides? Well the big one is cost. E-bikes currently cost several hundred dollars more than an unpowered bike. The price will come down somewhat over time but they'll likely never drop to the same price as an unpowered bike and I doubt they'll drop that much very soon because there is currently a big shortage in battery production capacity. However, look at it this way: let's say having an e-bike means you now bike to work instead of driving. That could mean reducing the amount of miles you drive by 50%. How much does half of a car cost? Probably a lot more than the price of an e-bike. Always struck me as odd that people won't think twice at dropping $20k+ on a car to drive to work but won't consider spending more than $1k to buy a bike to perform the exact same trip.

The other downside is that while e-bikes are great for commuting and running errands they're really not a lot of fun to ride recreationally. I may buy an e-bike for commuting but it would never replace my road bike for recreational riding.


What you want to look at is the gearing. Let's consider a regular derailleur-based bicycle such as this (source):

enter image description here

Lets call the number of teeth on the chainring / number of teeth on the gear you're using in the cassette the gear ratio. If the gear ratio is higher, for a given pedaling speed the bike will go faster. When you are climbing a hill, you will use a lower gear ratio versus going down hill or on the flats where you'll want a higher gear ratio. (*)

Generally the cassette these days has 7-11 gears and you have a double or triple chainring configuration.

If you want to deal with hills, you'll want a wide range of gear ratios. This can be achieved with a compact double (50t/34t) or triple in the front, and a cassette with a decent range in the back. Generally, the type of bike will also change the type of gearing available -- mountain bikes will have very low gear ratios but no high ratios since they don't cruise along at high speed. Road racers intended for flat use will normally have high gear ratios and not many low ratios. Hybrids and touring bikes will have something in the middle.

You can change the available ratios by putting on a different cassette (which may involve a new chain and rear derailleur depending on the length of the chain and derailleur capacity) or by replacing chainrings (but this is harder, and may require front derailleur changes as well).

More importantly, you need to learn how to select the right gear and keep a high enough cadence (rate of pedaling) -- usually around 80 rpm. This comes with practice.

I suggest going to a local bike shop (LBS) and asking them about bikes which would work well for your physical fitness and commute. We don't know how bad your health is or the type of terrain you're crossing, which would determine the appropriate gearing. Also, you may want clearance for bigger tires and other things if you're doing some off roading.

(*) This isn't everything that goes into gearing -- The crank arm length and outer diameter of the tire also contribute to gearing. However, lets neglect these, since the outer diameter is going to be around the same for all bikes of similar intended use and the crank arm length about the same for bikes of about the same size.


You didn't specify how long is your ride. But if half the route is off-road, then I would suggest a hard-tailed mountain bike with a triple front chain ring. The mountain bike will typically be geared lower than a road bike, and thus be easier for the hill climbs, while also having better agility in the dirt. The alternative is to get a hybrid with a bit wider tires (i.e. 700x35). Given you don't have a shower, I still presume you have bathroom or office you can change in. Dress for the second 15 minutes of the ride, and bring your work clothes in backpack, and bring a small towel to dry yourself. After getting to work, cool off first for about 10 minutes before changing. Baby wipes can also help.
