RAT Electric Bikes

Having waded through all the videos from the last two posts, here are my ‘Top 5 Affordable E-Bikes’, plus a DIY that probably trumps them all (in order of least expensive to most expensive):

Ride1up Roadster V2 $945 (free shipping)

Reminds me of my bicycle racing days with the Penn State team. I always rode a single speed bike during early season training. Except my training bike was A LOT more expensive than this. This e-bike looks like great fun and nobody is going to know it’s an e-bike. Perfect!

Gen 3 Flex $1,600 (free shipping)

Appears to be a solid package for the price.

RadCity 4 $1600 (shipping extra)

Appears to be an all-round solid package and a good value from a company that has a great reputation for building quality e-bikes. I also like the battery modularity meaning I can swap the battery out for an off-the-shelf battery rather than being locked into a vendor’s proprietary battery design/configuration.

Aventon Level $1800 (free shipping)

Another solid package for a price that won’t break the bank.

Magnum Metro S $1900 (shipping appears to be included)

Another great package at not a too terrible price point.

So with all these great options, why bother adding yet another to the list? Answer: because you’ll notice that every one of these ‘reasonably priced’ e-bikes use rear-hub motors. I don’t really have anything against rear-hub motors because that’s all I have had the opportunity to ride to date, until my mid-drive build is complete. But the reality is, mid-drive motors cost more than rear-hub motors, so if you’re going to build a ‘low-cost’ e-bike, rear-hub motors are the way to go.

Number 6 – you have seen this one before:

Contact JohnnyNerdOut and ask him to build you the Norco Scene step-thru e-bike he built for his in-laws. Including JohnnyNerdOut’s ‘build fee’, the whole thing should set you back about $2100 (plus tax and shipping). For this you get a custom built step-thru mid-drive e-bike that’s lighter than all but Roadster above. Note: JohnnyNerdOut would need to quote the actual price of this build. My number is a best guess, but I expect he would be delighted to build one of these beauties for you…

So that’s it. I really hope these last few posts help you decide which e-bike is best for your needs. Other than the Roadster piquing my interest, I am totally sold on building my own e-bikes. But I know this isn’t for everyone, so buying one already made is the next best thing!

Update: This e-bike from Ride1Up just popped up on my radar and appears to be a really good value at $1,045 (includes free shipping). It’s the Core-5. Check it out…

Update: Here’s another ‘reasonably priced’ e-bike I just discovered. This design is considered a ‘mid-step’ (not quite a step-thru). I like this one because it’s as simple as an e-bike can be. Note though, this is a single speed bicycle which means it’s not ideal for hilly rides. I like it because it’s simple, and for some, it might just be the perfect e-bike. Here it is: The RadMission 1 for $1200.

Need a really well designed step-thru? I would stick with Rad and consider the RadCity Step-Thru 3 Electric Commuter Bike for $1600.

If you’re looking to buy versus build, this video from Logan Moy at c|net is a great place to start.

Information overload…

No problem! Building isn’t for everyone. There are plenty of e-bikes on the market to choose from, but you must choose carefully. Below are a number of YouTube videos that will help you select the e-bike that’s right for you, and at a price point that won’t require a second mortgage. So first the videos, then I’ll provide some insight into the bike(s) I would choose if I wasn’t completely sold on building my own…

One would think that when you spend a couple hundred bucks for a used bicycle, you wouldn’t have to put a lot more money into it to make it yours. But the reality is you should expect to put another couple hundred into a fairly well maintained used bike (before electrification).

Sneak Peek

It’s January 14, 2022. The temperature in my garage isn’t terrible (though it will be tomorrow), so I’m going to start working on my mid-drive DIY project. Here’s a picture of my donor bike:

And here’s my starting parts list (shop around for better prices and a reliable supplier):

Well, that was easy! Here’s a 30 second video that shows how straightforward a mid-drive motor installation can be. The Bafang motor fit the Gary Fisher Genesis frame perfectly – no shims required!

And a few photos for your enjoyment:

This all went more quickly than expected, and the installation is very clean. I still need to torque everything down and figure out where wires need to go. Also, I need to modify the battery mount since the mounting holes provided set the battery too low on the down tube. I’ll likely be investing another 4 to 6 hours in this build before it’s complete.

It’s 1/12/2022 and this build is FINISHED! If I knew where my Staples ‘That Was Easy’ button is stored, I would have hit it. This build is SO much easier and cleaner than the rear-hub build, though a bit more expensive. It’s still really cold outside and there’s too much salt on the road for a test ride, but I’ll get out for my comparison test ride soon enough and write up my observations in a separate post.

Anyway, here’s the final build:

**update**

So, it’s now mid-February and I did get to test drive this bike. It was not pretty. The chain kept derailing, and power management was very strange. I’m now waiting for a new KMC 9-speed chain to arrive which should work better than the previous Zonkie chain on the 9-speed cassette and with the new Lekkie 46-tooth chainring (all explained in future posts)…

As a spoiler, here’s a picture of the bike today, including the new KMC X9 chain.

And one more thing: although the Lekkie chain ring is AMAZING, my chain alignment needs to be tweaked. I added this 2mm spacer that pushes the chain ring out a bit and that solved the problem. Note to self: spacers are cheap, so when you buy your Lekkie, pay the extra $5 for the spacer. You’ll be glad you did!

Having just watched JohnnyNerdOut’s ‘Norco Scene‘ video, I can’t help but think that the e-bikes he built for his mother- and father-in-law are perfect for casual and aging bicycle riders. The light-weight (relative to other e-bikes on the market), step-thru frame and ergonomics are dialed in for this type of rider.

Having done a little more research, I realize that Norco does make an e-bike, the Norco Scene VLT, available here for $3600. But referring back to JohnnyNerdOut’s video, I’m going to try to recreate his build to determine the final cost of his DIY Norco Scene…

Let’s start with the Norco Scene bicycle itself, then add the other components:

• Norco Scene 3 ~$800
• Bafang BBS02 750w mid drive motor – $480
• Includes hydraulic brake cut-offs and 500c display
• 52v 6ah saddle bag battery w/ Samsung 30q cells – $465
• Gear shift sensor for Bafang mid-drive motor – $29
• 6v Headlight for Bafang BBS02 motor – $13.99
• Add $20 for the battery bag, and that should just about do it

Before tax and shipping, I come up with a total of $1808. Compared to what’s on the market, except maybe the RadCity 4 (which is an awsome deal at $1600), this is a pretty sweet deal. Plus, YOU get to build it! What’s better than that…

As you know, my first two e-bike builds used the Voilamart rear-hub 48v 1000w motor. However, after watching several YouTube videos posted by JohnnyNerdOut, I became convinced that I really needed build a mid-drive e-bike, primarily to compare the build process and relative performance of rear- versus mid-drive e-bikes. So that’s what I’m about to do using my beautiful Gary Fisher bicycle and a Bafang mid-drive kit from Ebike Essentials (aka bafangusadirect.com).

I’ll provide more information about this kit in another post, but suffice to say that it was JohnnyNerdOut who convinced me to do this. Below I list a number of his videos which will help you get to know JohnnyNerdOut a bit better, will explain the difference between rear-hub and mid-drive motors (better than I can), and will share his experience upgrading various bicycles to e-bikes, which is what he now does for a living.

I found a wealth of useful (and some not-so-useful) information about DIY e-bike building on YouTube. Below, I’ll share several links those videos I found most helpful:

US Electric Bike Laws Explained from Bolton Ebikes

Interesting nugget in this video at 3:46 where he says “A low speed electric bicycle (<750 watts, <20mph ‘when powered solely by the motor’, and operable pedals) shall NOT be considered a ‘motor vehicle’.” This is important because federal law trumps state law. Therefore, the state cannot classify this (Class 1 or 2) electric bicycle as a motor vehicle.
