    Commuter Build - looking for input

    That's a lot of assumptions you've got going. None of which are correct - except for the ebike! S.

    Is there a good primer on RC Lipo? I understand that they are powerful but can be dangerous...

    Commuter Build - looking for input

    Well that is 2 votes for a 48v 1000w system. Looking at it closer it seems cost effective and is probably a great way to go for a first build. So where do I start looking for a battery pack? S.

    Commuter Build - looking for input

    Great replies, thanks all! And I've updated my profile. So the options are: * Mod my bike with a lightweight setup. * Get a Craigslist mountain bike and add a rear hub drive from ebay. What about a Bafang mid-drive? I read the install on one of the links in this thread and it sounded like...

    Commuter Build - looking for input

    Great breakdown, thanks! Great website too. I realize Houston is not a biking metropolis but I'll be coming from Alberta and the potential to ride year round is enticing. I'll be moving as close to work as possible too. With regards to ebike kits is a front or rear hub preferred? The rear...

    Commuter Build - looking for input

    Hi Gang, I''m moving to Houston for work and am planning on building an ebike to commute with. I love to ride and it's a project I've always wanted to tackle. My current bike is a GT Traffic 4.0 that I love. It's fast and easy to ride. I'm not sure if I should convert it or get a used bike...

    School me on hub drives

    What does the 'C' stand for? Is connecting those batteries a plug & play affair, or is there sodering involved? Is this kind of along the line of building a pack using dewalt batteries? S.

    School me on hub drives

    Ohhhh... That makes perfect sense when I see it in print! So a 14S battery pack will give me about 48V. What kind of range can you get from that? And how big is it? The connection I am not making is why people are using SLA batteries when something small & powerful like this is available...

    School me on hub drives

    So the 'S' designation refers to a single cell in the pack, with a small voltage, that is dependent on the battery type? S.

    What is the difference between a 48v ping type & a 14s, which is also 48v? S.

    School me on hub drives

    The Amped geared hubs are supposed to be very high quality. They are produced at their own factory in china, to their own specs. S.

    School me on hub drives

    It seems like the way to go is to buy the best motor you can afford, followed by controller then batteries. That way the motor will be able to take the upgrades later, the controller is relatively cheap in comparison so that can be upgraded as needed & the batteries will need to be saved up for...

    School me on hub drives

    Thanks guys. The learning curve is pretty steep & there is a lot of digging through posts required to get the big picture. So the 9c motor sounds great! I've read some about the Crystalite motor as well, as the high power offering. What is the difference between the two? The other big motor...

    School me on hub drives

    I've been doing a ton of reading about the various ebike options but am still a little in the dark. I'm just going to put a few questions out there... For what application would you select a front hub drive over a rear? What application for fixed vs geared? I know with golf carts the way the...

    Budget RC Build Recipe?

    Roger that. So would it be used instead to keep the hub gears for regular cycling & the single sprocket for electric? S.

    Budget RC Build Recipe?

    I checked out that adapter for the 3 speed hub. When installed it allows you to have a single speed off your crank, then 3 speeds off the motor? Has anyone here built one like that? That sounds like the ideal setup for a chain driven build. S.

    Budget RC Build Recipe?

    Thanks guys! Matt it was your recumbent build that led me here. I am going to do like you say & start real simple with a friction drive. Keppler I've been through your builds & they are fantastic! I like your latest build (I'm slowly reading through the 30+ page thread) but am leaning more...

    Budget RC Build Recipe?

    I wouldn't be adding the hub for gearing, just as a pre-built off the shelf method for incorporating a freewheel. That way it can stay engaged with the tire all the time. The chain drive seems to be a natural extension of that... Hadn't considered chain noise though. I'll check out that 3...

    Budget RC Build Recipe?

    I've been thinking on this & have come up with a design idea. It'll be a friction style roller drive, with the roller being a chain driven bicycle hub. That'll take care of the freewheeling aspect. What kind of motor do I need to run in order to attach a sprocket onto the shaft, to drive...

    Hillhaters Mk 3 Friction drive !

    Thanks for the clarification. I really like your design! So will it ride on the tire all the time, or will it sit just off then "snap" onto it when you roll on the power? I'd like to build something very similar... S.

    Budget RC Build Recipe?

    Wow! I've been reading through the friction build logs all night! I think that is exactly what I am looking for, for a first build. My wife would like just a little extra oomph to help on the hills & they seem to fit the bill nicely. I like how they are lightweight, compact & easily...

    Hillhaters Mk 3 Friction drive !

    Forgive the noob question... From the pictures it looks like the motor casing itself is what rests on the wheel? So you have the motor's internals mounted up solid & the casing spins around that? Is that a specific motor design, that turns the whole unit instead of just a shaft? S.

    Budget RC Build Recipe?

    Great community here, everyone is real helpful! I definitely want to go chain drive. I saw the reducer built by Recumpence & was thinking something along the lines of that, but I haven't looked at the other examples yet. While I don't have a cnc I could probably cobble something together out...

    Budget RC Build Recipe?

    Hi Gang! I didn't see an intro forum, but I've been interested in electric vehicles for a long time. I've looked at building a set of bikes for my wife & I with electric assist, but was never impressed with the offerings. Then I saw some of the RC built bikes! I've read through a bunch of...
