Yup (Link Removed - No Longer Exists)

Chain is generally more efficient than a belt. http://www.cyclingnews.com/features/chain-drive-or-belt-drive-whos-faster/

Yup, in the same way an automatic tranny does to a car driver. If all I had to do was spin the crank on my bike, it would get very boring PDQ. It doesn't take much intelligence to shift a derailleur, they are inexpensive, reliable, and last for years. -- Just because we can does not mean we...

With that 250 watt limit, the strongest and most practical system would be an eBike with PAS mid-drive. A package delivery business might allow the OP to get a fleet rate and meet his price point. Vespas are utilitarian enough, but the CVT transmission needs frequent maintenance. And if you...

EBR isn't good enough for you and you use this forum to recruit for another? That's low.

It has happened... with no torque arm, or an improperly fitted arm allowing the axle to spin.

Aluminum dropouts can fracture with hub motors. The problem can occur when the tire looses traction momentarily, such as on pavement with a sandy surface, then grabs traction, again.

Mids put more load on the chain and rear cluster so they can wear faster than a standard pedal bike, but you will normally get a LOT of miles before that maintenance is necessary. Shift sensors were not part of the original Bafang mid package because they really are not necessary with the...

Cargo bikes tend to be big and heavy, and when used to haul groceries and other cargo they can sometimes be challenging. Tern has come out with a brilliant solution. https://tinyurl.com/y8pohk4t

For you curious gearheads, here is a video showing the disassembly of the Shimano STEPS drive unit. The language sounds like Dutch, but if you don’t understand it the mechanical information is still there with his commentary muted. There is a brief pause at 16:20, then it resumes at 16:40...

I don't want to rain on your parade, but maybe you should do some reading over at Endless Sphere. What your are looking at will disappoint. You get what you pay for. IMO, you would be better served spending more and getting a Bafang mid-drive.

I sometimes wonder who the real elitists are. If/when national intervention happens, you will likely still be able to have your Moped but will need to register it, attach a plate and buy a tab, and be restricted where you can ride it. The current California Class-I, II and III power-assist...

With population growth comes the need for more control to maintain order, and the fastest way to regulation and taxation is abuse of privilege. When I read about the Mopeds in bicycle disguise that the people at ES are creating, I cringe. In the US, our focus has been moving away from...

Some PAS systems claim to be programmed to pause while you shift. That electronic 'clutch' isn't always reliable. If you want consistent, slap-free shifting with a rear hub or mid-drive, go easy. Just like with a manually-shifted derailleur on a regular bike, keep the pedals rotating but do...

With a MAC, thicker 13G spokes would be a good idea [14G is the norm]. Two-cross lacing is common. Choose a quality double-wall rim. After 500 miles, have the spoke tension checked. Some MAC specs and info are here https://em3ev.com/shop/mac-5001000w-motor/

I'd bet that Shimano's STEPS advertising creates some hassle for dealers from concerned purchasers. :eek: Our host, Court, has probably ridden more eBikes than anyone else on the planet. In his mid-drive motor comparison he said, “...the Shimano drive system. Their motor is quieter... than...

FYI: Because the power is routed through the chain to the rear gears, a 250 watt mid-drive is much stronger on hills than a 350 watt geared hub. With a hub's limited internal gear reduction, you need to maintain a quick pace up hills to keep the motor from laboring too much. It has been stated...

> I am hoping to buy an e-bike soon, and am somewhat surprised at the weight of many of them (>45 pounds). I think Trek has one or more mid-drive eBikes under 45 lbs. Check the reviews and specs here at EBR for others. If you go with the popular add-on mids made by Bafang, the motor and...

If you find lift worthwhile but don't like the restraint of clip pedals or straps, try "half clips". The Zefal Cristophe are nice and durable (Link Removed - No Longer Exists) , and they work great with a moderately priced alloy pedal like a Wellgo (Link Removed - No Longer Exists) .

Motorcycle engines in sport bikes tend to have peaky powerbands. That narrowness of energy creates a ride where you keep the engine revs boiling while you tap the shifter to maintain the rpm. Good fun with a motorcycle on a twisty backroad. Mid-drive PAS eBikes with the same narrow peak power...
