Dobry den, Bateria 48V 20Ah 960WH Model: FP4820R0BC
Dobry den,
dna 26.6.2025 som si cez Alliexpres objednal elektricky horsky bicykel VARSTROM so stredovym motorom Bafang 750W. Prisiel mi v poriadku a som spokojny, ale ked som si chcel objednat este jednu bateriu do rezervy 48V 20Ah 960WH Model: FP4820R0BC, ktora sa montuje do spodneho ramu a je takeho obdlznikoveho tvaru, tak mi posielaju link len na baterie co sa montuju na ram bicykla. Je to katastrofa, ked si kupite novy bicykel a nemate moznost si objednaj taky isty Model: FP4820R0BC baterie. Co nevidia kde sa monuje ta bateria a ako vypada !!!!!! Poslal som im aj foto!!! Absulutne mi pokazili veskeru chut. Snazil som sa ju najst na internete, ale nikde nie je .... co ju vyrabaju Martania ??? Prestanu komunikovat a .... Katastrofa, fuj hanba !!!!!!!!!!

I ordered bike kit
The kit arrived, I am still waiting for the spacers.
Commande de mon Ebike
Commande de mon Ebike - Cola Bear arrivée dans les temps et superbement emballée. Aucun problème à signaler.
All great after initial teething problems
Delivery was super quick to the UK, within 2 days from UK stock! Shame they sent the wrong wheel though… (500w rear hub instead of front hub). However after some initial issues trying to contact them (their WhatsApp number on the main page was saying invalid due to a single digit typo, so tried email but was getting no response for 4 days over the weekend). The good news is that once I found the correct WhatsApp number in the Contact Us page, response time was super quick and they sent out the correct wheel without delay for next day delivery, and they covered the return postage for the wrong wheel.

Zero customer support from the manufacturer or their supplier when you have issues. Simply ignore messages. So if you have an issue good luck you are on your own. The displays and controllers have very limited configuration if you want to change any settings. In example you cannot change the speedometer settings when it does not read the amount of motor magnets correctly.

Received TSDZ8 2 e-bike kits from Varstrom. One kit came with a complete order. The other one had a wrong display model. The working kit works very well. Very quiet, great torque. I reached out to company on WHATSAPP and they arranged to send me a replacement display and I will send the wrong one back to them. I would give a 5 out of 5 if my order was fully correct. I’m hoping to get the display soon and I’ll update the review.

Terrible service
Terrible, items marked as available and shipped within 8 days, all of a sudden go out of stock, replacement solutions are then also out of stock and you find yourself much later than 8 days none the wiser if you will get your item or even a refund when cancelling (asked but not received)

I have brought a set of bafang display and BBS02 motor they sent me something rong but I complaint and they helped me very gently and very fast I'm very happy thanks to Varstrom and I'll recommending to buy from them 😊 ☺️
Very poor service
Very poor service. I ordered two sets with two additional displays. When the shipment arrived, one display was missing and I immediately wrote to the company. A month later, I still haven't received the display. When they take the money, everything is fine, when there is a problem created by them, you can't find it, they don't respond or respond but don't do anything

I got good advices
A very satisfying purchase.
When spending this kind of money online, one always has concerns. At each stage, Varstrom proved to be trustworthy and competent. All questions received a timely response and communicated attentiveness to the customer. The delivery time was well within the promised limits. The package arrived in very good condition and the bicycle was very nicely protected and secure. Assembly required was really the minimum one could expect. The reward for all this concern and effort is a formidable vehicle that satisfies on all the important levels. The comfort is incredible. The power is ample without being brutal. It handles very well. The gear development is close to perfect. Nothing feels or looks "cheap". It must be noted (and this is not a negative comment) that it is a very big bicycle and quite heavy. It is not at all for small riders. Overall, the closest thing to a criticism one could make is on the order of documentation. There is almost nothing instructive in the supplied manual about assembly or maintenance. Only an experienced mechanic should prepare this vehicle for the road. With that in mind, I thoroughly recommend Varstrom and the New Cola Bear (where did they get that name?) 2.0. It is very much worth more than the money.

Very good site for buying a BAFANG motor to equip an electric bike and for purchasing a new electric bike.
Very fast delivery.
Always available to advise on technical and assembly questions.

Poor customer service.
I ordered an ebike conversion kit and it arrived incomplete. I emailed Varstrom about the missing items and the representative was defensive and unhelpful. It frequently took more than a day to respond to and email and took nine days to get them to send the missing items. I had to repeat myself and send pictures multiple times. The whole interaction was just frustrating and unprofessional.

Tilasin Varstromilta bafang keskimoottorin, ensin tilasin loppuunmyydyn mottorin koska nettisivuille ei oltu päivitetty vielä tätä. Asiakaspalvelu otti yhteyttä ja kysyi haluanko uudemman version. Ymmärsivät myös vaihtaa pakettiin tulevat muut osat vastaamaan uutta kokoonpanoa kun mainitsin siitä. Hinnat on todella kilpailukykyiset eikä firmasta ole pahaa sanottavaa.
Heillä on jopa youtube- kanava jossa esittelevät tuotteita ja asennusohjeinen päivineen.
Toimitukseen meni se n. viikko mikä on normaali aika EU:n sisällä. Hyvin paketoitu paketti, eikä tule toimituskuluja tai tulleja erikseen. Tämä toimii!
Ainoa miinus tosiaan on tuo että nettisivut eivät välttämättä ole tavaran varastossa olon suhteen ajan tasalla, mutta tämä lienee perus ongelma aina kun kyse on kiinan tuotteista joita myydään euroopassa.
chargeur de batterie Kit Bafang BBS02
Problème avec le chargeur de batterie pour le Kit BBS02, le chargeur ne s'allumer plus après 4 utilisations...j'ai contacté Mr Kong de Varstrom, après l'envoi de photo corroborant mes dires, j'ai reçu en garantie un nouveau chargeur et problème réglé !
I used Varstrom twice now- Best price !!
I used Varstrom twice now, 3 years ago and a week ago
The best way is to chat with them via their web chat. keeping in mind they are on HK time not UK time.
I ordered the BSS02b 750w with a 20Ah battery and it arrived 3 days after order ( 27th in the morning , 30th in the afternoon )
on my first order they replace a burned out battery connector and were always very help full
NO WARRANTY on Varstrom Europe BAFANG middrive kits
I bought two Bafang mid drive kits, with battery, from the Varstrom Europe dealer on AliExpress, in August 2024. One BBS01-350W and a BBS02-750W. Including batteries it cost me 1200 euros.
3 months after not so very intensive use, the BBS01 started showing Error 30 on the screen, intermittently. The support person of Varstrom Europe, which did not have any products in his store anymore, told me to check all connections and see if any cable was broke. So I did this several times. At some point, the screen would not turn on and my motor became useless. He still was telling me I needed to check all cables.
Finally I replaced the screen and the cable that connects to the screen. Still the screen was black. Then he told me he can SELL me a controller, which was probably broke.
I told him the motor was purchased brand new, and he should provide warranty. But he told me, if I buy a new controller, he would provide warranty. Not for the whole kit I purchased previously.
I have no way to get any support or warranty for a product I payed a lot of money for. Above all, after 3 months of use, it is broke and it can be thrown away.
The practice of Varstrom Europe, is unacceptable.
I would recommend nobody to purchase anything from this store. There are reliable other sellers, that can provide ADEQUATE support and live up to the warranty of BAFANG.
