Used Ebike from Craigslist - worth it?

I'm looking to get an ebike for my 14 mile flat commute. It's open and mostly flat so I'd like to be able to go 35mph. I've been looking into building my own, but I ran into this bike from a local guy who builds lots of powerful ebikes. He's the owner of SV Ebikes so he's experienced in building the...

Re: Best Value fast ebike for my commute?

It looks like the "Vector Storm" frame will suit my needs nicely, but I'm wondering if there's enough space in the frame for the battery size that I'd need. Battery-size max dimensions: 44.5cm x 11.5cm x 9cm Can i get a good 52v 20ah battery in those dimenisons? Will the leafmotor 1500w motor fit in...

Re: Great ebike frame the doesn't look like a dirtbike?

Looks like its a really compact rear susp system. https://bikemagic.com/bikes/giants-maestro.html But any of that style, where the bottom mount of the rear suspension is close to the BB and the shock goes straight up... saves a lot of room for more batteries.

Currently Giant FS bikes with their "Maestro" suspension system seem the best, but GT has some older models that qualify.
Do you happen to know the model of the Giant bikes with Maestro suspension, or which model GT bikes were worth checking out?
Thanks for the info so far!

Great ebike frame the doesn't look like a dirtbike?

I'd like to build a dual suspension ebike that can hold a fair amount of batteries. I noticed most dual suspension mountain bikes don't have much space in the frame though. I do see a lot of frames available that are made specifically for ebike builds and look great, but I feel like they will attrac...

Re: Best Value fast ebike for my commute?

Great info! Just a couple questions: 1) Is the main advantage of getting a phaserunner controller that it's smaller in size and has technology to make the motor quieter? 2) Does the 1500W motor you mentioned above (LeafBike) come available without the controller? I see the "kit" without battery is ...

Re: Best Value fast ebike for my commute?

You must remember that all those DD kits covinently forget about thermal protection. Say you have hilly commute , so you risk burning your motor every ride. There no way around it Controller need to read from motor to protect from oveheating . read motor temp outside of motor? If you dont burn moto...

Re: Best Value fast ebike for my commute?

Since you have a decent budget, I’d get the leaf bike 1500w motor since it has a good reputation and is very efficient. Any direct drive motor will be dead silent with an FOC/sine wave controller like the phaserunner. Motors will handle just about any voltage, but it’s a matter of how long. If you ...

Re: Best Value fast ebike for my commute?

Another question: do these hub motors typically come with built-in controllers? That would be nice so I'd have less wiring and less components mounted to the bike frame. Most folks wouldn't recommend a hub with a built in controller, since both the motor and controller produce heat, which isn't eas...

Re: Best Value fast ebike for my commute?

Thanks! Also really appreciate the responses so far. So it sounds like my best bet is going to be a mountain bike with dual suspension (aluminum rather than carbon) and a direct drive 1000w hub motor, plus a 52v battery with at least 17.5ah capacity, and a controller to go with it. So which motor sh...

Re: Best Value fast ebike for my commute?

More suspension better, unless its cheap sucky suspension. No, you aren't going to average 30 mph, unless you cruise 40, in any city. I wont knock the mid drive, but my advice to use a rear direct drive hub motor for your particular commute remains the same. I speak from 5 years of e bike commuting...

Re: Best Value fast ebike for my commute?

Let me know if you guys think this is a good idea: - Full suspension OR hardtail mountain bike (used from Craigslist) - I'd like to add 'drop bars' to this bike eventually. I know this complicates things to make a 'frankenbike' but I like the idea - I'd also like to add smoother tires for better eff...

Re: Best Value fast ebike for my commute?

Cruising speed is much easier to calculate than average so we'll go by that in this post. Cruising speed of 30-35 mph is easily obtainable with so called generic 1000W chinese hubmotor kit. I think they will last 14 miles at that speed unless you live in a very hot climate..particularly if you peda...

Best Value fast ebike for my commute?

I'm looking for advice on either a store-bought ebike, or else a kit that I can add to an existing bike (bike to be purchased used, likely) for my commute. My commute is 14.5 miles with only 200' of climbing. I'm a pretty avid cyclist so a non-electric bike works fine, but I thought there's opportun...

Re: Fast Electric Cargo Bike for my Bay Area Commute

Mid drives would suit your needs quite well. I highly doubt you'd be able to install a Bosch motor on your Surly, as those motors are for manufacturers. Companies like Specialized, for example would use their proprietary blend of parts - not good if something were to break a$ then you are a b!t(h t...

Re: Fast Ebike for a tough commute

I ride the 20 miles to work sometimes, and on both my bike and my wife's bike I drain the 1000wh battery each way maintaining about 30mph. If you want a 40mph top speed on level ground with an upright bike, you're going to need a 2000wh battery to go 34 miles at 30+mph. Thankfully you will contribu...
