how do electric bikes work on hills

Hello. I need an electric bike with a range of 40 km and the ability to handle very steep hills. I plan to ride 20 km one way and 20 km back with the possibility of charging along the way. As far as I know a bike with at least a 1000W output would be optimal. Do you have any other recommendations regarding specifications Or if you know of a specific model could you please let me know I live in USA. Thank you.

Mid-drives are generally better suited for long slow climbs. Conventional direct-drive hub motors are not suitable for long hills.

Is it uphill both ways LOL

Lets be clear about how steep the hill is. A 7 gradient might feel quite steep for a human cyclist but most electric bikes are perfectly fine. Visit draw a map and then select the Show Slope box on the left. This will display the slope of the route as a percentage. If the slope is less than 10 you can climb the hill using a hub motor with sufficient torque. If its over 10 youll need to purchase a mid-drive or direct-drive hub and add coolant Statorade to the motor. You wont find 1000W mid-drive e-bikes in the EU. EU e-bike regulations limit power output to 250W and top speed to 25 kmh. Otherwise youll need to register as an S-pedelec.

Hills drain your battery a lot. At least in my experience they drain your battery 4-5 times more than flat terrain. I live in a hilly area and Im only getting about half to a third of my expected range. So my advice is to get a big battery. Get at least 19Ah900Wh. …Motor output measured in watts definitely helps but in most cases theres a legal limit on power though many people overlook that. But torque is the most important. Torque is often measured in Newton meters Nm. If you need me to explain what torque is please reply to this comment. Id be happy to help. I highly recommend a mid-drive motor for hill climbing. Even with lower wattage these motors can reliably produce over 100 Newton meters of torque up to 160 Nm. Also because the power is transmitted directly through the gears the power transfer is more efficient when climbing. Still if youre looking for a simple easy-to-use hub-drive motor I definitely recommend Bafang. All Bafang motors seem to have 80 Newton meters of torque but be sure to check; some motors have different winding methods for higher top speeds and lower torque. In my experience when I owned one myself it was more than enough for hill climbs at 20 mph. If you want to continue to increase your range significantly I recommend building a bike with a Grin Technologies GMAC motor. This is a geared hub motor with very high torque but it also has regenerative braking for hill descents. With 100 Newton meters of torque its the best hub motor for both climbing and descending in your current situation. However keep in mind that these are meant to be added to your bike as a kit not for personal use. Also because they range from 1000 to 2600 watts they may violate local laws. However how do local authorities determine whether youre riding within the speed limit Anyway when choosing a bike consider other factors. For example whats your budget Do you use it for commuting Are there laws regarding electric bikes in your area And so on.

Im not an expert so I cant recommend it. However dont forget to consider the quality of your brakes. If you commute to work and climb long steep hills your return trip will also be long and steep.

I weigh 100kg and was worried Id need 1000 watts or mid-drive power to climb a hill but with 20-inch wheels and 350-watt hubs I climbed over 150 meters in less than 2km without a problem. On steep sections youll need to pedal slightly as if you were pedaling slowly on flat ground. You can climb without assistance but its quite slow and seems like it would be a strain on the bike. I cant honestly say anything about range. More watt-hoursamp-hours mean longer range but it also comes at a cost of weight and cost.

In that case Id advise against buying the Aventon Level. I think its called that because it can only be used on flat ground. It gets really muddy on hills. Fortunately I live in Minnesota so the terrain is relatively flat. Furthermore the customer service is abysmal so Id strongly advise against the Aventon.

In my opinion if you plan to pedal you dont need 1000W and you can save a little on the motor and battery. On the other hand if youre looking for something like a moped that doesnt require pedaling 1000W isnt enough. I recommend at least 1500W. I live in the mountains of North USA and am a heavy rider on a heavy bike but Ive been using a 750W geared Bafang motor for years with good results. I rarely use it at full assist usually cruising between 175 and 350W. I can get about 30km on a 14AH battery. My wife has a 250W torque-sensing mid-drive which is more efficient and can get 50km on 11AH but shes half my size. Im not a huge fan of direct-drive motors. They can overheat at very low speeds such as when climbing long hills and the motor cogging when coasting is frustrating.

Biktrix Ultra Duo. I tried it once to climb a hill for testing…

My Bafang BBS02 can deliver 750W of power but on long rides I rarely use more than 300W even on significant climbs. My wife and I often ride 35km up steep hills up to 600m. We each have a 12Ah battery but we pedal quite a bit. A 17Ah battery would be enough to power these rides with just the throttle. For more information about the bike visit

You dont need 1000 watts unless youre towing something heavy. 250 watts is more than enough for steep climbs. Even if you can only generate 50 watts at a slow pace youll still get about 300 watts of sustained power. This is roughly the power expected from a world champion cyclist in the Tour de USA. You can even climb hills. What you really need is a larger battery.

The Bezior XF 200 is a great value for the money. Im from Portugal but the bike arrived from Poland in a week.
