Finally converted bike into a FWD ebike. Got a 350w hub branded Zemake from aliexpress plus controllers. It was my first ehub wheelbuild using Sapim 13/14g spokes. Built a 13s1p small battery using 21700 cells (roughly 150wh). The hardest part was figuring out settings for the generic s866 screen. A lot of trial and error but finally finished it. On steep uphills, I use some throttle as I gear down. Still testing how many miles I can get from the small battery.

Here is a stock picture of the new Gazelle Ultimate C380+ It is a type 3, with Bosch electrics, a Gates Belt, and a CV shift.



Stock picture as I have not received mine yet.

Those are great bikes, hopefully you can actually get your own pictures soon.

When I look at the price of a Ribble 26 pound eBike, 40 pounds seems excessive. My 36 volt KBO Hurricane version 1 was 37 pounds when it arrived, but I was able to reduce that weight to 32 pounds with changing a few parts I could replace easily from the excessive part bin my lady keeps trying to toss - wheels replacement saved the most weight I still have been unable to find a carbon fiber frame to really change the eBike's weight. I did it the weight reduction as I lived in an apartment 3 flights of stairs up, and 32 vs 37 pounds was a great change going up and down to my home. I always charged on the patio as it is a stealth bike with almost non removable battery that buried in the downtube. I have since retired and moved to Oregon from Las Vegas and have not found my charger in the storage unit. The 250 watt rear hub motor was enough in econ or lowest setting to average 12 miles an hour safely in Las Vegas early morning and afternoon traffic. Without the ability to charge it for the moment, I have been riding my single or fixed gear bicycle here in Oregon. I will post again when I am once again am riding the KBO version 1 Hurricane with the belt drive that is silent and quite enjoyable. With its 43 mile range, and ny excessive weight of 200 pounds I have done about 6,000 miles on the KBO but am trying to lose a bit more weight and will be 80 years old next April...


I like the look of your bicycle but the weight would kill my enjoyment in stop and go traffic. A 26 pound Ribble is my dream eBike until they can make them lighter with much longer range with battery and motor future improvements...

​​​​​​​Ebikes, for the most part, aren't for weight weenies. 40lbs for a build is fantastic.

This bike has been a background project for a few years now. It started as a very used Trek 820 mountain bike and an even more used xtracycle cargo bike extension. The most unique thing about this bike is that the "StokeMonkey" drive system is right side drive and fully freewheeled so that the motor and pedals can each spin independently of each other. On traditional StokeMonkey systems, the motor drives the left side of a crank like a tandem rider would. So when it moves the pedals, you need to pedal with it. These systems would typically have a freewheel on the motor so that you could pedal without having to also turn the motor. A side benefit of keeping the pedals completely independent from the motor is that I could implement a torque sensing bottom bracket - which I did.

I created the right-side independent drive by using a White Industries crank freewheel putting a reverse ratcheting ACS "SouthPaw" freewheel on the Crystalyte drive motor. In order to mount the SouthPaw, I had tor replace the normal freewheel threads on the motor and replace them with some left-handed threads. I did this by literally sawing the threads off with a hacksaw and then carefully filing resulting surface flat with a file. I then bolted and bonded a right side bearing cup from a bottom bracket to that surface. It is a fortunate coincidence that bottom bracket threads are the same as for freewheels. Or if not exactly the same, very, very close.

This last picture is a proof of concept mockup before any of the parts were stripped and repainted. I decided to just remake the wood deck rather than refinish it. You can see that the original plan was to have the motor in the rear triangle - and I would have preferred that. But I was uncomfortable with the tight fit. Some of the gaps were pretty small. And moving the motor did free up that area for mounting the battery, motor controller and 12v DC converter.

Nice.

Wow! That's an amazing build Jay Turberville

My latest find, fix and flick (althogh I might keep this one), is a Bridgestone branded Japanese domestic market bike. I bought it in bits, with a seized rear wheel.

These have a few weird things: stainless steel wheels with side pull front brakes (roller brakes + 3 speed IGH on the rear), tyre pressure sensors, a built in lock for the rear wheel that also locks the steering, solar recharged rear lights.

The electric is a 24v system, made by yamaha. The 8.7ah battery is at least 10 years old so pretty low capacity. I'll repack and upgrade that to 16ah.

My Motobecane HAL eBoost m600. Its kept me on the trails through a cancer diagnosis and 6 months of chemo. I am a Clyde, so having that 120nm Bafang motor has been great.

Delightful in many ways. Rest day bike, long day bike, not-sure-I-wanna-ride day bike, in a hurry rides,…

Out and about evening ride...

When I have not been riding any of my bicycles much lately, the e-roadie is a nice way to ease back in - get more aerobic miles and survive the hills with enough energy to enjoy the rest of the day.
Definitely a nice ride option on a yardwork day

Wasn’t planning on immediately getting a front rack, but while I was getting accustomed to the rear-heavy ebike it reared like a balky horse while being walked on a downslope, and a counterweight shot to the top of the priority list. The Minoura rack appeared on a bike kitchen’s eBay for cheaper than Amazon, and the gloriously ‘90s colored panniers at another. Now it handles much more like the folding bike I rode before, just stiffer and heavier. My lifting capacity is right around forty pounds and I can lift (and pull back down!) that front end but lifting the entire bike is a trial.

at least the Sedona decals and the Nashbar accents are similar shades of purple

Not sure how I got into my mid-60's before discovering this, but am glad I took the plunge!

Here's my latest conversion and a peek at my next one.

Purchased this Biria EZ-Boarder in 2024. Took me a year to get around to it, but spoked up an AKM128 hubmotor for the rear wheel. It has an 800W sticker, which I'll have to replace to be legal in Illinois, but I did use a 20A 48V KT controller. We ride it at 12 mph,

Intent was a bike we can get on/off without getting a hernia, The seat is pointed to the sky because my wife likes it that way,



The motor is officially advertised at 6.2 lbs, so 1 1lb for the freewheel and 1 1/2 pounds for the alloy rim/spokes seems right. Add 6 pounds for electronics/battery. Bike is probably pushing 50 lbs,


Technology now allows tiny batteries like these, Top is 150WH, while bottom is 230WH and both can flow 20 amps if needed. At 8 WH/mile, one is good enough for an evening ride. I can carry a spare in the handlebar bag,


Nothing fancy, Five level PAS and throttle.


Biria sells a front drive model like this for $1995. I could have gotten a used Biria donor for $200-300, but I bought it new for $699. Put about $400-500 into the electricals.

Parked outside the Titanic Captains house in my town

Finally got a chance to swap out my handlebars for a riser bar, change the front headlight to something SLIGHTLY brighter (since it's only a 36V system my options are a bit limited), and do a 14 mile evening ride. It was quite enjoyable, especially since the temp was a comfortable 74F when I went out. Now I just need a nice set of wide folding pedals, which for the life of me I can't seem to find...

way 2 many upgrades to list them all but it deos have two motors and three batteries going on 3000 miles with this one

That's a real "trekking" bike. Is the front hub a 1500w DD?
