Hello,

I am new to the forum and I honestly hope I have not violated any rules by this post of mine..

I did quite a research and found that this forum has quite a lot experts on e-bike matters :D

Can you please give me some advice about the following product?
https://m.gearbest.com/electric-bikes/pp_009380899937.html?vip=16936804

I intend to buy it and I would like some opinions..

I will give you some insights from my point of view.
My only experience regarding electric vehicles is a Chinese electric "scooter", the DUY F-Wheel D1 (gearbest). I bought it hoping that it can service me for a home-work-home commute of about 4+4 kilometers (approx 5 miles). This pretty much did the job, despite some extra steep hills in the area (where some times I had to push the scooter for 20-30 meters). It had 28km/h speed unassisted on flat ground and decent range of about 10 miles. But I sold it again, as I realised that 1)the problem of climbing 2)the very small size (which causes some extra dangers), are show-stoppers.

Now I need to get a similarly powered vehicle, but with pedals (for me to assist better uphill) and to have theoretically unlimited range, so I can travel farther in the city.

Keeping that in mind, and the fact that I have a tight budget, would you recommend this product, or you consider it waste of money?

Thank you in advance!
Chris
 
Waste of money, if budget is a big consideration combine a used bike with a 1000W hub motor kit and a battery either from EM3 or a member here.

Got it! I appreciate the advice, really.

The thing is, that I already own a bike, this one (700c - if i m not mistaken):
https://www.idealbikes.net/?section=2150&language=en_US&itemid1494=2192&detail1494=1

Would you suggest I go electrifying this one?

When you say "1000W hub motor kit", could this be the case:?
https://www.ebay.com/itm/48V1000W-26-Front-Rear-Wheel-Electric-Bicycle-Motor-Kit-E-Bike-Conversion-Kit/291973640306?hash=item43fafc3072:m:mB-OMU8i-ySU3XbPDRth-dg&var=590969387982

I saw a thread in here discussing about it (https://endless-sphere.com/forums/viewtopic.php?f=3&t=98443) yet I think the problem of mine as well is that these kits are easily found for 26" and not 700c...

And one more question :roll: ... How much weight would the whole conversion add?
 
You seem to have a very nice bike already. As you also need it to be able to climb you might want to consider a mid drive kit. PSW power sells kits and batteries from within the EU so no tax or import duties. If you want to stay legal you can get the 250W kit with torque sensor the TSDZ2: http://www.pswpower.com/ven.php?cargo.2017-2s-gaym with a bottle battery: http://www.pswpower.com/ven.php?cargo.2018-ay-hhpt or Hairon battery: http://www.pswpower.com/ven.php?cargo.2017-bv-s42x

Then you'll get something like the bike at the bottom of this page: https://endless-sphere.com/forums/viewtopic.php?f=6&t=235&start=1750

More info on the TSDZ2 here: https://endless-sphere.com/forums/viewtopic.php?f=28&t=79788
A lot of pages with good info and help there. There is even a thread with info on custom firmware to upgrade the kit at a later stage: https://endless-sphere.com/forums/viewtopic.php?f=30&t=93818&p=1442282

Between you and me, i do not want to be limited by 250w, i need to build a decent e-bike.. :wink:
yet thank you for the valuable information.

If you pointed me to some 500+w solution I would very much appreciate it!
 
Look at ebikeling (inexpensive), em3ev or ebikesca (more expensive) for 700c hub systems easily above 500w or consider a BBS02 mid-drive (25 amp controller and 52V battery will provide all the power you need). As noted, not legal in the EU.
 
Keep in mind that this forum is heavily oriented around DIY (doing it yourself). If that's you too, then building your own is clearly the way to go. You can get more speed and range if you custom build to your situation and preferences. If not, the bike you referenced will probably be a nice fairly inexpensive and effective way to commute - assuming your hills aren't super long or have grades greater than about 5%. That bike also has the added advantage of being fold-able so you might be able to bring it inside and mitigate potential theft issues. It probably isn't a great bike, but I think it could still provide utility at a reasonable price.

I already did (in two links)...

But if you don't even take the time to read all the info that is there then just buy a ready made bike. As converting your own bike will probably end in a stranded project by not reading a manual or all the info provided here. And if you really need a good commuter then just buy a moped/scooter. I bought an almost new scooter (only 22km ridden) for €100,- with dead lead acid batteries from standing too long. Then swapped in a LiFePo4 battery pack to get a scooter(moped) that can do 45km/h and has a range of 30-50 km (depending on load&speed) for around €500,- total. I have ridden it for 5250km thus far in less than a year.

Good luck.

Great to see you wanting a decent ebike ;)
Besides that power wattage are just numbers, there is no set definition for power levels, as long as you aint doing wheelies and speeding past people, your fine. I notice now that Greentime on Aliexpress is now selling MXUS motors, like the 3000W, its a great direct drive motor. More power the better!

Looking at the bike's specs and your requirements, it looks like the bike would be a good fit, if the 40km range is enough.

You may be able to build a better one for that price, or one that costs less if you stick with your minimum specs. It depends on the cost of a decent donor bike is in your area. Where I live, I can get good deals on really nice mountain bikes if I'm patient, since the sport is very popular, and people trade up a lot. If you don't have access to decent/cheap donor bikes, then you might not save much, building to that bike's specs.

If you really want a lot more range, then a kit may be the best bet, since the battery is really where the money goes.

You are right about that @SlowCo. But no, I prefer to do the effort to build one closer to my needs and a bit of "futureproof". I have started studying carefully the links you posted to me.

I do, @markz, yet, I want to avoid to get in too much of complexity. I will try to find that perfect balance of perfecture/complexity.. :)

I understand that now @wturber. And I start to like it very much! I wish there where similar communities here in Greece, so I can share the interest/hobby.

Anyway, I thank you all who posted some reply to me, really.
You gave me very VALUABLE resources to start with..
I m going to make my research now on how to make my kit and come back to you for validation ;)

I am very happy to be in this forum! :D

I see now this is 9,3 Kgr!!! Are you serious? No way I wont add that much to my bike! :mrgreen:
I better stay at 500W... :roll:

Naaaaaaa that is a typo, you are missing a 3rd 0 :wink: 5000W!

Seriously, there is the 1500W that lots love, but I understand the want for nimble and light. Not sure how much it weighs, compared to the MAC/BMC. I dont really keep up on weights, as my body fat alone weighs a lot :oops:
 
Here is a 500 watter

https://evfittinggreentime.aliexpress.com/store/group/Brushless-DC-Motor/313864_251592060.html?spm=2114.12010608.0.0.17e56bfeLYVsHO
High Quality 48V 500W brushless gearless hub... US $73.58 then shipping would be about a Franklin.

Buy your controller, three throttles (2 for spares), torque arms. Since they also sell the KT Display, I am sure their controllers would be ready for it. Battery from www.em3ev.com or Unit Pack Power on Aliexpress/Alibaba, same with OSN Power.
 
Ok, after some searching I came up with Mac motors rear hub drive on 48V, 10Ah battery from pswpower:

Do I forget something necessary?
 
Please don't . It looks like another cheap chinese electric bike.

I bought one look 99% similar for 899. I think I pay 898$ more than what it worths.

Hi @wesleyp! I made my decision, after the valuable info in this thread, I will build my e-bike. Please see my next posts, I have already came up with a suggested set-up, it will cost around 650$, and I will use my existing bike (trekking 700c).

Please take a look at this and if you have any comments do tell me :)

:lol: :lol: :lol:
I consider it a valid point, really!!
I see "weird people" bragging about how they had their bike down to 12,8 kgr... (from 13,5 kgr it was previously)... and I think... "o-m-g just eat a sandwich less and go biking...! It would have saved you some 100 bucks...! :D

Nevertheless, besides the fun, I find it funny that people in here do not talk about conversion weight so much..!
Why?
 
I am excited to see it. I think it will be a better decision to go this way.

I wish I can afford to buy a Haibike but for some time it seems hard for me. If what you did works maybe I will follow your footsteps.

Why?

Batteries. No electric motor bicycle can be both light and practically functional - hills, reasonable distance - and it seems that the heavier they are, the more functional. So one leaves behind the concern for weight.

You aren't alone there. In fact that's so common, that apparently "250W" just means "bears a 250W rating label, for compliance." What it really means in practice, I'm not so sure, but I think it's fair to say that owners of 250W drives aren't limited by 250W in every case.

The Mac from EM3 is a solid choice. Great all around motor. One thought -- for your application, 10T or 12T wind might be better than 8T. In general, lower wind counts = greater top speed, higher wind counts = greater torque. With a 700c wheel, you might value the torque a bit more than a theoretical higher rotational speed.

I cant speak to your specific battery choice, but can recommend EM3 as a battery vendor from personal experience. They are known for quality construction.

Enjoy!
 
Go watch some GCN on their Youtube channel, bunch of Lycra Roadies, circle jerking about 100 grams.
Heck they even bring out the crack dealers weigh scale with a large smile on their face. You can just see the foam on the sides of their mouths, if its really saliva foam or not.
