Is there a limit to safe downhill speed on a bike

6 min read

Asked by: Lisa Johnson

There is no limit to safe downhill speed on your bike. The limit is when you come off your bike. In which case even a low speed crash of 20 to 30 mph can be pretty nasty on chip and seal type surfaces or where there are obstacles (oncoming traffic anyone?).

How fast can you ride a bike downhill?

Technically speaking, bikes can go downhill at extremely high speeds, provided that all the conditions and factors are in their favor. For example, on the downhill parts of most regular situations, the speed of the bikes will peak at about 17 to 30 mph (27.3 to 48.2 km/h).

What is the max speed you can go on a bike?

Professional cyclists can achieve a 45-MPH top speed on a bike using only raw power to propel themselves over the road, facing the wind. Todd Reichert is the world record-holder for unpaced bikes or bicycles that rely only on leg power, setting a top speed of 82.82 MPH. Competitive cyclists are a different breed.

What is the fastest downhill speed on a bicycle?

Full details of the MTB ridden by Elias Schwärzler in his 272 km/h bike speed World Record.

How fast do Tour de France riders go downhill?

In Tour de France downhill sections, they can go at speeds as high as 65 mph / 110 Km/h, even losing the motorbike reporters.

Can you go 50 mph on a bike?

I know going 50mph is a rare event on a bike but I’ve had done it twice on a bike tour I was in that had pretty high elevations. one was a 6,000 ft ride with one of the hills(in my opinion a mountain) being a ~1,800 ft climb and went around 52 mph going down it.

How fast do Tour de France riders go uphill?

Based on my research, it seems that most climbs are done at around 12-14mph–and we’re talking about some serious gradients and after several hours in the saddle for days on end. Of course, many of us could probably climb pretty well with all those hours put in.

Is 25 mph fast on a bike?

Professional bicycle racers can usually maintain 25-28 mph on flat ground. But for a beginning road cyclist, an average of 13.5 mph is very respectable, especially on a longer ride.

How do pro cyclists ride so fast?

But the other major way that professional cyclists go much faster than the rest of us in a race like the Tour de France is their expertise in drafting or slipstreaming. This is where they cycle “on the wheel” of the rider in front so they are protected from some of the air resistance.

What is a fast average cycling speed?

Ride consistently and get fitter, and you should be able to maintain a mileage per hour in the mid-teens (around 15.5mph/25kph) over several hours – Strava reckons that’s the average speed for rides logged. To hit an average speed of 20mph/32kph, you’ll probably have had to put in lots of systematic training.

What is the longest bike ride without stopping?

Ultra Marathon

  • Solo man: Christoph Strasser, 2014, who averaged 16.42 mph (26.425 km/h) riding 3,020 miles (4,860 km) in 7 days, 15 hours, and 56 minutes.
  • Solo woman: Seana Hogan, 1995, who averaged 13.23 mph (21.3 km/h) riding 2,912 miles (4,686 km) in 9 days, 4 hours, 2 minutes.


Should you pedal downhill?

The energy you put into pedaling downhill is largely lost to air resistance, so there’s no real point in doing so unless you’re racing. But, that said, maintaining an easy, slow cadence downhill, where you’re not actually exerting much energy, may help keep your legs warm and ready to go at the bottom.

How fast do Olympic cyclists go?

History of track cycling



There are 12 different events, and the races are held in a bowl-shaped arena, called a velodrome, that is 250 meters (820 feet) round (though sizes can vary from track to track), with racers riding counterclockwise and achieving top speeds above 70km per hour (43.5 mph).

Is biking 30 miles a lot?

Cycling for 30 miles for two hours is considered a good pace for slow, fast, and experienced bikers. So, you would not have to fret about going faster than that. However, there’s a huge possibility that you would not feel too good by the time you finish this mileage.

How fast should I cycle for my age?

18–25 years: 17–18.5 mph. 25–35 years: 20.8–21.7 mph. 35–40 years: 18.6 mph. 45–50 years: 15 mph.

Can you outrun a bear on a bike?

Considering that a black bear can sprint more than 30 mph, cyclists should remember that you can’t outrun a bear on a bike unless you have a very long head start, an unencumbered racing bike, and the abilities of a time trial champion.

Is 15 mph fast on a mountain bike?

Values range from 3 mph for technical trails up to 15 mph for paved greenway paths. The average speed singletracks riders maintain on the trail is 6.98 mph so if a trail lists an average speed above this – it’s fast. Otherwise, it’s a bit slow.

How fast can you ride a mountain bike?

The top speed of a mountain bike is 35mph to 38 mph. This is the top speed most riders could reach with 2” knobby tires and high gear (3×9). But it’s not the same if you ride with different tires width and gears, as we said above. Mountain bikes typically have three types of gearing: low, medium, and high.

How fast can a mountain bike go on flat ground?

How Fast Can Mountain Bikes Go On Roads? At 300 watts power output, a mountain bike on a super flat road’s surface can go up to 23 mph, when the grade increases to 5% the speed can drop dramatically down to 12.4mph due to the weight effect.

What is 27 speed bike?

The 27-speed bike, its flywheel is generally the same as the 24-speed, the difference is only the largest front gear plate adjusted from 42 to 44, so that the nine speed ratios under the large gear plate are larger than the 24-speed, suitable for people with good physical strength.

Why do mountain bikes only have 11 gears now?

So why do mountain bikes have less gears? Mountain bikes have less gears for quite a few reasons, however the primary reasons being less maintenance, lighter weight, and the need for only the quickest shifts when running into such a varied terrain.

What are the 7 gears on a bike for?

A 7-speed bike is a great bike for a person who rides on tricky terrain. It’s main purpose is to let the bike adapt to rough conditions and accommodate inclines, bumps and other difficulties. On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill.
