Need opinion on 26" E-bike

Hi guys,

Just want to know your opinion on this ebike on the Craigslist. Thanks!

Give the ad's location, I'd say you need a hub motor capable of generating a fair amount of torque for hill climbing. I'm not sure that the generic hub motor on this bike is the right candidate. It's also installed on a front suspension fork, which if the fork is aluminum, is a big safety no-no, especially since I don't see torque arms. The fact that the bike only has 3 gears, may also cause some disappointment since you'll be pedaling, too. I'd say the price is too high for what you're getting.

FYI--You can get a similar, generic e-bike brand new for less. http://shop.vendio.com/remo032/item/.../?s=1263113762 However, not knowing the specifics on your commute, size and if you're planning on pedaling, I'm not sure what's a better match for you.

Thanks. The XB-310Li resembles the bike on the ad. The main difference seems to be 6-speed vs 3-speed. Did I miss anything?

The Xtreme folder also has disc brakes and a slightly more powerful 300W motor. If you have $1000 to spend, you might take your time, determine your needs and shop around for an electric bike that will suit your needs. I'm not recommending the Xtreme, I really don't know anything about the brand. I just thought you needed to know that the price on the ebay bike seems high, given the specs. The new Xtreme folder is a close match but, on paper, has better specs and is cheaper.

It's not worth it. If you're in SF, you need a much larger motor. And one that IS NOT mounted on front suspension! What were they thinking?! I bet those forks are even aluminum. The battery won't get you far on your hills, either.
For that price, you could get a motor (hub or otherwise) that will provide a lot more torque and a battery that will actually last. Mount it on your favorite bike and you're good to go.

I commute by ebike from San Francisco to Brisbane for since 2007. I can confirm most hub motors may not be suitable in the hilly areas unless you pedal alone with it. I have multiple hub ebikes as well as chain drive ebikes. My personal favorite is a non-hub motor for the city commute due to high torque with high speed.

I was wondering on the generic e-bike how much distance would you get on a charge. On the website it says 20 to 25 miles per charge. I have the IZIP 24V10A Battery which is rated at 12 to 20 miles per charge. However, I only get around 9 miles per charge. I do pedal the entire time. I do have the some big hills on my commute. Any insight would be appreciated.

Jerry,

Don't rely on mileage claims on any e-bike, especially if the stock batteries aren't LIFEPO4. Even LIFEPO4 batteries may not be high Cs and may not give you as much mileage as you want. If the care and handling of LI-POLY batteries wasn't so risky, I'd be tempted to try LI-POLY packs since most have a much higher C-rating. If only A123 batteries were available for e-bikes at an affordable price.

Clearly, rider size and road conditions affect mileage, but I'm shocked you're only getting 9 miles on your Currie SLAs if you're pedaling. I live west of Glacier National Park and have much steeper hills to climb than you. I've traveled 25 miles and still had power to spare in my one SLA battery, but I only use power assist on the hills and pedal then, too. However, I'm a woman and probably lighter than you. But still, perhaps your SLA batteries were older. I'd suggest you move to another battery technology when your SLAs die. You should also install a battery volt meter/power analyzer. Hobby King has a good one for right around $25. You really don't want to over discharge any form of battery--it's a sure way to prematurely kill them.

To get the actually mileage rating, you simply divide the number by divide or three. Then you can get the more realistic figure in cluding hills & stop & go traffic.
