What Dealers Say About Working with Us
Mark Evans ★★★★★Owner of CycleTech Electric (USA)
I’ve been running my e-bike shop in Texas for 8 years, and I can say JUESHUAI bikes are the real deal. Fast shipping, no drama, and customers love the ride feel. Sure, sometimes we need to chase down spare parts, but they’ve never left us hanging. Solid crew — if you're in the business, keep an eye on them.
Daniel Brooks★★★★★Product Manager at UrbanRide Scooters (Canada)
These guys make scooters that sell themselves — good performance, sleek design, and dependable after-sales support. Orders usually arrive within 10 days, and any issues get sorted fast. Only complaint? Their product catalog is growing so fast, it’s hard to keep up!"
Anna Fischer★★★★★Procurement Lead at RideOne Mobility (Germany)
JUESHUAI is one of the most structured suppliers we’ve dealt with. Their documentation is clean, their compliance certificates are up to date, and delivery schedules are followed accurately. We requested several packaging adjustments, and they were implemented efficiently. Communication could be faster during peak seasons — but overall, they're a long-term partner we trust.
Lars Andersen ★★★★★ Founder, Nordic Care Wheels (Norway)
’ve been in the mobility business for over 20 years, and JUESHUAI is one of the best partners I’ve had. Their electric trikes and mobility scooters are well-designed and durable. Sometimes communication gets a little lost in translation, but their team always follows up and makes things right.
Jorge Ramirez★★★★★Scooter Shop Owner (Mexico)
I have small shop in Guadalajara. We sell scooters and trikes for local delivery guys and older people. JUESHUAI send good ebikes, strong and fast. I do not need clear customs she will help me do all and delivery to my shop. My English no perfect but they help every time I have question. Delivery okay, price good. Thank you for support!
Jean-Michel Kouassi★★★★★Lyon Scoot'Electrique (FR)
J’ai commencé avec JUESHUAI il y a deux ans, un peu par hasard, et franchement je suis resté. Leurs trottinettes sont fiables, bien finies, et surtout, mes clients les adorent. Le service client est plutôt réactif, même si parfois il faut un ou deux rappels pour avoir une réponse (c’est la Chine, hein 😅). Mais bon, ils tiennent leurs promesses, les délais sont respectés, et les produits font le job. Pour moi, c’est un vrai partenariat gagnant.
