I ordered the Altis Sigma MX from Bonnell Bike and the entire experience was flawless. Shipping from the USA warehouse to Texas took only 4 days. The bike arrived fully assembled and perfectly tuned. Customer support answered all my pre-purchase questions within hours. This is my new go-to shop for e-bikes.
Samantha Miller –
Absolutely love my new Surron Light Bee X! The team at Bonnell Bike was incredibly helpful in helping me choose between the Surron and the Altis Delta. They gave honest advice instead of just pushing the more expensive bike. Shipping was fast and the bike arrived in perfect condition. Highly recommend.

Great experience overall. Bought the 79Bikes Falcon and it arrived well-packaged from the China warehouse. Took about 12 days to Australia which was reasonable. Only minor complaint is that I wish the tracking updates were more frequent during transit. Bike itself is incredible.

The Altis Sigma MX is an absolute monster. I’ve owned gas dirt bikes for 20 years and this thing rivals my 250cc. Bonnell Bike shipped it from their USA warehouse and it arrived in 3 days. The race display with lap timer is a game changer. Worth every penny.

Noah Wilson –
Ordered an Altis Sigma from the Canada warehouse. Delivery to Toronto took 5 days which was great. The bike is phenomenal. I’m giving 4 stars instead of 5 only because the assembly instructions could be clearer for first-time e-bike owners. Once assembled
