Awesome off-road machine

This is my second electric mountain bike. The first was a Rurui XT10 with hub drive and it was not well suited for off-road riding. This bike is! I like more serious off-road riding. I just completed my first 30 miles, mostly off-road. It included long, steep, loamy hills. My last ride was a 22 mile loop that has over 2,900 feet of ascent. Lower rider fatigue than other bikes as well. This off-road riding tends to eat batteries but I went about 30 miles on this charge and had 52% remaining without a range extender battery. Here is a YouTube video of parts of that 22 mile loop: https://youtu.be/NcHmBKLUrgU .

I am so happy with the purchase of my Ultra FS Pro 3 . I still can’t believe how much floatation is created by the 4” tires on semi packed snow. The battery performance is amazing as well. I had been considering a Biktrix purchase for a long time. I am so happy I pulled the trigger , now I can’t wait for summer riding. Thanks Biktrix. 56 yr old KP from central B.C Canada

Super bon vélo de qualité

Mes premières impressions sur Biktrix, et bien j'ai reçu mon vélo FS-Pro2 en deux semaines, assemblages rapides, et faciles pour ce qui restait à faire. Beaucoup de vidéos et documentations, pour un anglophone c’est merveilleux, mais pour un francophone heureusement, on peut tout traduire ou presque aujourd’hui… Alors on se débrouille, j’ai donc réussi à tout comprendre. Tout ce que je trouve qui manque avec l’envoi, c’est une liste des composantes par vélo, ça permet rapidement de trouver des pièces de rechanges locaux au besoin ou d’avoir plus de pièces en lignes.
je n’ai rien èa dire, j’ai écrit (en traduction) et j’ai rapidement reçu du support pour commander un kit de disque de feins, et même si nos deux provinces son assez éloignée, j’ai reçu ça de façon rapide en quelques jours avec un suivi de ma livraison. Je suis technicien concepteur mécanique de 30 ans d’expérience, j’ai aussi été responsable de la qualité dans mon entreprise. Je peux affirmer que c’est pas juste un beau vélo, mais aussi avec une qualité soignée, je ne suis pas un grand expérimenter des vélos, mais des motos oui et tout ce qui ce conduit hors route, la qualité et la… et le choix des composantes aussi, on doit apprendre à conduire c’est bête Ultra… le seul problème, le moteur est puissant… c’est pas vraiment un problème
PS : Le siège confort, je le recommande deux batteries c’est pesant, mais ça donne de l’autonomie leur choix d’accessoires sont tous de qualité pour avoir équipé nos vélos…
Note : le jeu de roues supplémentaires de 27,5 po, il devrait y avoir une option pour la casette et le disque de frein en supplément à choisir, car dans mon cas, ils serviront en mode Streets, avec des pneus plus moins larges sans crampons, pneu pour piste cyclable, et augmenter l'autonomie, alors je veux faire l’échange rapidement selon mon parcours.
J’adore mon FS- pro2… je le recommande,
