Your bike weighs 150lb!! My gosh, it's an electric moped, not an ebike. A collision with a pedestrian on a sidewalk or trail would be quite dangerous. The law should include a weight limit as well as a power or speed limit for an e-bike classification.

I'd say if you can take it up a flight of stairs by yourself, the weight is ok.

Without lithiums using off the shelf batteries the heavy load also climbed a 10,005 foot high volcano with all that weight getting a round trip speed of 20 mph on a 72 mile round trip.The same bike weighs a total of 65 lbs including batteries for 40 mile trips at legal ebike speeds of 20 mph.A 200 lb lycra racer can do some damage at 45 mph too! Whats your point?

My point is obvious. To me, an e-bike that weighs 150lbs is not an e-bike. I don't like to see posts here about electric mopeds disguised as electric bikes. I can probably make it up that volcano faster than any of the lycras if I carried 40 lbs of bionx batteries with me.

Without 100 lbs of NON lithium 33 Ah batteries on a 45 lb Huffy bike the same bike will go 60 miles on 14 lbs of batteries and a 5 lb motor system.= 65 lb ebike. The range would be even better with a 30 lb aluminum bike with slicks instead of knobbies.= a 50 lb ebike capable of 1600 watts of efficient power or 200 watts of power above 90% efficiency inbetween.You slect your power and speed requirement by voltage or gearing.

Hey, if your motor system is only 5 lb, I'd like to see that on a 20lb bike. Add 10 lbs of Lithium batteries and the bike should be light enough to ride on slick 28c tires. Then add 100 watts of your own pedal power, and you should still be able to get 60 miles (i'm just estimating). A 35 lb ebike that goes 60 miles with 200 watts continuous assistance! I'd be really impressed if that were the case.

This is how to build a nice lightweight electric road bike. Putting an ugly assed can motor, chain and sprockets on a weight weenie bike would be a crime.

IMO putting a heavy X-lyte hubmotor on any bike is a waste of batteries.

Here's where it's at. A mid-drive that runs the motor through ALL of the bicycle gears. The efficiency is so high that a small battery pack will give you 60+ miles of range on an ebike that's a joy to pedal.

That's a Heinzman hub motor in the pic.

https://www.austinev.org/evalbum/465

66lbs, top speed 42mph, minimum range 70 miles, maximum range 160 miles.

Putting a heavy ass dollar store bicycle on an efficient motor is a waste of batteries.

It must be a joy to pedal.Under motor power alone it wont go 10 miles up a small hill.

What is so efficient about brushed a Heinzman hub motor ? How do you put a bike on a motor that works ?
