Hi everyone, Apologies for the lack of updates this month. I’ve been busy with other projects and couldn’t dedicate as much time to the bike as I wanted. Today, I’m sharing the current state of the CAD model along with some key design decisions aimed at improving compatibility and ease of...

Thanks for the point on the screen. I'm aware of that and my workaround is to not have a screen at all. At the end of the day a simple matrix led for battery stat, 5 leds to indicate assist level and a couple of buttons on the handlebar is all that is needed in my opinion. Also less stuff that...

The range extender is something i was already planning on. About the battery it will be an integrated battery with a carbon enclosure but it will be extractable trough the motor mount for serviceability.

Hey Freda, my initial plan was to go with the M820 motor, but I couldn’t get my hands on one. Luckily, someone here offered me an M510 at a great price, so I decided to go with that 😅. As for the linkages, if you check my earlier posts, you’ll find the full simulation along with the geometry...

Hello everyone, It’s time for the first update on the CAD work for the eBike build. After some fine-tuning of the geometry to improve tire clearance at full drop, I’ve now moved on to drafting the front triangle and deciding on the battery configuration. Battery: After reviewing various...

About printing a frame i guess you refer as for visualization? That's one of the steps i will be taking to ensure proper functionality before commiting to get tooling and so on. Cost of titanium prints tends to go from volume of the part so i will be doing some clever topology optimization to...

The thing is that i'm not particularly a fan of bikeparks they are fun but i prefer exploring singletrack. So no lifts for me😅 I will take a look at the geo on the knolly for sure. Motor i got it thanks to one person that saw the thread and sold it to me for really cheap.

Mini Update on the Motor: I’ve decided to design around the M510 motor after receiving an incredible offer that I couldn’t turn down. Once it arrives, I’ll begin working on the CAD model. For now, the first step is determining the battery capacity and selecting the cells, which will help me...

That sounds great! Most of the uphills I ride are singletrack. They’re not overly technical, but they have one steep section after another, which makes it really exhausting. By the time I reach the top, I’m completely drained, and I have to take it easy on the descent to avoid any accidents. It...

Geo Day For this frame, my main focus is downhill performance, so I'm aiming for big suspension travel: 190 mm in the front and around 180 mm in the rear. Ideally, I’ll go with full 29" wheels, using 2.5" or 2.6" tires up front to plow through the roughest terrain imaginable. Although the focus...

I was doing exactly that but moneywise i was going to spend about the same as me doing the full thing beeing restricted to what the manufacturer decided before me, so i will take the work and time and do it all myself. Regardless if someone is willing to send me a frame i can 3dscan it and...

Amazing response, 2.4kg is for a battery of about 700wh if i go with smaller motor the battery would drop in capacity too to about 450-500 going to 1.6 -2kg depending on the cells selected but this weights are only achievable with really high end pouch cells i should be able to get them trough a...

That's the idea of the project to innovate and try and make something better than what the market offers. At the end i will be spending the same or more than a high end frame but it will be exactly what i want it to be. And bafang to my knowledge is pretty easy to tune and get as a standalone...

No, m820 in 2.3kg, m510 2.9, m560 is 3.4 and triple the power, and so only motor is 1.1kg extra plus the battery for m820 would be about 1.7-2kg using standard cells and for the m560 3-3.5 so total minimun 2.6kg extra. And about running it on less power it seems a waste, same performance but...

Hey, Yes, I looked into it, but the shock options are really limited, and it only offers 150mm of rear travel. My goal is to stick with 180mm rear and 190mm front travel. As for the motor, I’m not looking for something overly powerful; I just need enough to help me extend my rides. A more...

Backstory & Introduction Hi everyone, my name is Martin, and I'm a bike enthusiast. What frustrates me the most is being physically exhausted after just one downhill ride. So, what's the solution? An eBike! However, finding an eBike with aggressive enduro geometry that doesn’t cost a fortune...

Hello everyone! I'm thrilled to embark on a new project that I'll be documenting here—building a long-travel eBike designed for aggressive enduro riding, entirely from scratch. This journey will cover every aspect of the build, from deciding on the ideal geometry, moving into CAD design...

Hi, sorry to bother. Anyone has experience buying from 4leaf? They have the cef50 frameset with motor and battery for a really good price with included shipping. https://lfbikes.com/products/m820-carbon-frame It's the first frameset i am thinking of buying and have probably too many questions...

I I've seen those frames, they are really interesting, the lce930 or the lce971 but no xl sizes from them and measuring 196 size L is way too small...

Hi guys, new here. I'm really interested in building one of these frames but can't seem to get it in a reasonable timeframe. By any chance, does anyone have an XL frameset to sell? Thanks
