Above all, there are also Sonic Evo family from Bulls 2022 will see the return of fresh Bosch e-MTBs, most of which rely on the 750 Wh battery and the new control unit with numerous smart features. We have the details on the new Bosch system summarised in a detailed article. The Sonic E-MTBs from Bulls continue to cover an enormous range of applications: an E-Hardtail (29-inch or 27.5-inch - 120 millimetres), Trailfully (29-inch - 120 millimetres), All Mountain (29-inch and 140-150 millimetres) and an Enduro (29-inch - 160 millimetres). However, the Enduro models all use the previous Bosch drive with a "small" 625 watt-hour battery, while the other model series offer a choice between the new and old Bosch system. This is exciting for those looking to save money: if you can do without connectivity, fine adjustment of the support levels and 20 per cent more battery capacity, some Sonic models are still available with the old Bosch unit.
More battery capacity is primarily noticeable through longer trail or touring fun. However, in addition to long-lasting adrenaline rushes, the thicker energy carriers also cause lasting headaches for bike designers. This is because small frame sizes in particular are difficult to realise. The larger battery (7 cm longer!) increases the minimum length of the down tube. For the Sonic EVO AM all-mountain fullys with the new Bosch system, Bulls has dispensed with the S frame size that exists on most other Bulls platforms. One reason for this could be the 45-degree battery removal upwards from the down tube. If you're looking for a 750cc Bosch bike in a smaller frame size, you'll have to take a look at the Copperhead models from Bulls.
You can also enjoy the smart Bosch system comes the Copperhead Evo e-hardtail. Three models in 29 or 27.5 inches, 120 millimetres of suspension travel and aluminium frames create an attractive entry point for e-bike newcomers. The prices range from 3999 euros to 4599 euros. Finally, the Copperhead Evo AM - a touring fully with 150 millimetres of suspension travel and MX wheel mix - is also equipped with the newly presented Bosch system.
