Any recommendations for a lightweight ebike conversion kit for road bikes?

[Katrina92]

My favourite local bike shop offered me a good deal on an Addict eRide, but I didn't like the bike's 'racer' geometry, which is a shame, because the bike looks awesome.
At 73 my body likes the more relaxed geometry.

One kit that looks interesting is the Boost kit from the UK. The two negatives with this kit is they presently only offer their kits in the UK and they have a 25km motor cutoff. They're very similar to the Mahle setup.
There's also BikeOn, but there has been some problems with their earlier kits.

Another kit is Skarper

The e-ride version does mess with the original bike's geometry, and it's not for everyone. I've looked into Boost too, and it just seems way too bulky!
What's your take on Skarper? I've noticed you've been mentioning it a lot.

I'm with you on that. I checked out this Keyde product, and it seems to have a fake thru-axle (with two bolts securing it from the sides). What do you think about it?

I don't think it is "fake", it's just the way they made their motor work with a thru axle frame.

I think the Skarper looks weird, but it looks like it might actually work on carbon framed bike. What I really don't like is the price.

One very last post on this thread. OP, post up what you decide to do, if anything.
I see the Keyde, laced into a 700c wheel with phone app and no battery, is now on sale for $516.96 and there is an AliExpress $70 discount listed for a total of $446.96. Battery sold separately or choose your own 36v battery as it isn't proprietary. Compared to anything else that could work with a thru axle carbon bike with 142mm OLD width, there is no comparison - that is if it works as advertised.

Keyde seems too bulky

我不认为它是“假的”，这只是他们使用通轴框架使发动机工作的方式。

You're right

I agree, it does look kind of weird!
The price is definitely steep.
I wonder who would actually buy a Skarper. Really not gonna affect the handling at all?

One very last post +2, but this time I mean it. Good luck and I hope you end up with what works for you.
If you mean too heavy the motor itself adds 5# (minus the weight of your bike's current hub), the 7ah battery <3# - if listed weights are accurate. So if your current bike weighs 18# you would end up at ~26# which is the same weight as the Scott Addict eRide 30. Not too shabby.

If you are fixed on a hub-drive install torque arms. This will prevent the dropouts from stripping.

Thanks for your help! I'll think it over.

Here's another cheap-ish drop bar hub motor ebike I just saw about. This one from Poland; EcoBike Forest. Not sure if they sell where you are, especially with Mr. Orange's love of tariffs. But it looks a good solid package. Nice drive train, tyres etc.

EcoBike Forest

The EcoBike Forest is a fun, free-rolling drop bar e-bike that’ll make light work of day-to-day commutes and will also be viable for getting out and about exploring at the weekend. It’s not without its foibles, but it’s affordable as these sorts of bikes go and I certainly enjoyed my time with...

I finished this one today. My friend's wife and I hid it under a blanket in my friend's garage. He does not know about it yet and will get curious to peek under the blanket. I took a dropbar bike and made it upright and gave it beefy tires. It has a DM02 motor and Shimano GRX gravel specific group set.

You really enjoy utilizing the UPP water bottle batteries. Assuming that's the 48v version, it is rated at 7ah. Is that really enough for the intended use? Cause I have a 52v 6ah pack that the kids basically have to charge every other day. W/ the 48v 15ah pack, they only have to charge once a week.

I have those UPP water bottle packs too, 36V10AH and 48V7AH, both with a nominal 350WH rating, Real life is about 300 WH, and I typically get 33-34 miles if I run them flat. AT home, we rarely go farther than 22-24 miles, Come home and recharge for the next ride,

I have a really old Luna 52V6AH mini, Have only used it about six times in 9 years, It's just too unwieldy. A 13 cell 48V pack with 21700 cells makes for a easy to carry spare though,

If you’re aiming for something close to the Mahle X20 in terms of light weight and stealth, the best options are kits like the Swytch (especially the newer compact versions), the Lightest Bike Kit from Europe, or even Zehus, since they’re all designed to keep things minimal without adding much drag when the assist is off; while nothing matches the refinement of the X20, these are probably the closest alternatives unless you can find a used Mahle setup or donor wheelset to transfer onto your Scott Addict.
